VerdiBlot

About us

VerdiBlot is a universal, PFAS-free, 100% biodegradable Western blot membrane for sensitive, low-background results.

VerdiBlot is a universal Western blot membrane manufactured by LAM-X a.s. in the Czech Republic. It was developed for researchers, laboratories and life-science organizations seeking sensitive protein detection, very low background, ultra-low autofluorescence across 280–800 nm and practical compatibility with established Western blot workflows. Supporting wet, semi-dry and dry transfer, fluorescence and chemiluminescence, multiplexing, staining, stripping and reprobing, VerdiBlot helps laboratories obtain clear, high-quality results across routine and demanding protein-analysis applications.

Sensitive detection with very low background
At its core, VerdiBlot is designed to support the everyday needs of modern Western blotting. Laboratories must often work with low-abundance targets, limited or valuable samples, weak antibodies and complex experimental conditions. In these situations, membrane performance directly affects whether a result is clear, reproducible and useful. VerdiBlot is intended to provide strong protein detection and very low background, giving researchers a clearer view of their targets and helping faint bands remain distinguishable from non-specific signal. This combination is valuable in routine experiments as well as demanding applications where sample availability, sensitivity or image quality is critical.

Designed for established Western blot workflows
VerdiBlot fits into established Western blot procedures and can be used with wet, semi-dry and dry transfer systems. It is compatible with common laboratory practices and is designed to require no or only minor workflow adjustments. This allows research teams to evaluate it directly against the membrane they currently use rather than redesigning an entire protocol before testing a new material. VerdiBlot typically does not require a separate PVDF-style methanol pre-activation step. It can normally be wetted and equilibrated in an alcohol-containing transfer buffer, with brief ethanol wetting available when needed. The result is a membrane that offers practical handling while supporting familiar transfer and detection methods.

Ultra-low autofluorescence across 280–800 nm
The membrane is compatible with chemiluminescence and fluorescence detection, two of the most widely used approaches in Western blot analysis. For fluorescence applications, VerdiBlot offers ultra-low autofluorescence across 280–800 nm, supporting a broad spectral range and compatibility with commonly used fluorescent imaging channels. Very low background is especially useful in fluorescence imaging, where non-specific membrane signal can reduce contrast and make low-intensity targets difficult to interpret. A clean background also supports clearer chemiluminescent results and can give researchers more flexibility when optimizing exposure conditions. VerdiBlot has been evaluated across different proteins, sample loads, antibodies and imaging approaches, with results demonstrating its suitability for sensitive and demanding Western blot applications. As with every membrane, final performance depends on the complete experimental system, including sample preparation, transfer settings, blocking, antibodies, washing and detection equipment.

Multiplexing, staining, stripping and reprobing
VerdiBlot supports multiplexing, allowing researchers to detect several targets on the same membrane when the antibodies and imaging system are suitable. Multiplex analysis can reduce the amount of sample required, save time and provide more information from a single experiment. It is particularly valuable when researchers need to compare a target with loading controls, study several components of a pathway or analyze multiple markers in limited material. The membrane’s very low background can help preserve separation between detection channels and improve the clarity of multiplex images. Internal field experience has also shown that the practical limit may be determined by the detection system and assay design rather than by the membrane alone.
The membrane is built for staining, stripping and reprobing, enabling multiple analyses from the same transferred sample. This is important when sample material is scarce, expensive, difficult to obtain or ethically sensitive. Instead of repeating the entire experiment for every target, researchers can remove bound antibodies, reblock the membrane and probe it again under suitable conditions. VerdiBlot’s mechanical durability and protein retention support repeated handling, while its low background helps maintain useful image quality across sequential analyses. The exact number and efficiency of stripping and reprobing cycles depend on the target, antibody pair, stripping conditions and laboratory protocol, so gentle conditions and stepwise optimization are recommended.

Performance in demanding applications
VerdiBlot is relevant to laboratories working with low-abundance proteins, low sample concentrations, low-volume samples and antibodies that produce weak signals. Users and application work have reported clear detection in workflows involving faint targets, phosphoproteins, human or clinical material and a range of protein sizes. These applications illustrate the value of combining strong signal with very low background. Rather than making a universal claim that one membrane must outperform every alternative in every experiment, VerdiBlot is offered as a technically capable option that laboratories can assess under their own conditions. A side-by-side comparison provides the most meaningful evidence because it shows how the membrane performs with the laboratory’s samples, equipment, buffers and antibodies.
Independent application work has compared VerdiBlot with conventional PVDF and nitrocellulose membranes in different Western blot workflows. Reported outcomes include very low background, clear bands, detection of faint targets, multiplex compatibility and successful stripping and reprobing. Other evaluations have involved stain-free gels, phosphoproteins, recombinant proteins, human-cell lysates, mouse-liver lysates and clinical sample material. These studies demonstrate the range of conditions in which VerdiBlot can be used while also showing an important scientific principle: membrane performance depends on the target, protocol and imaging setup. VerdiBlot therefore emphasizes transparent evaluation and practical laboratory evidence rather than unsupported promises of universal superiority.

A PFAS-free and 100% biodegradable alternative
Sustainability is a defining part of the VerdiBlot concept. The membrane is PFAS-free and 100% biodegradable, providing an alternative to conventional PVDF membranes made from persistent fluorinated polymer materials. To our knowledge, VerdiBlot is currently the only Western blot membrane offering 100% biodegradability. This distinction gives laboratories an opportunity to reduce their reliance on fluorinated materials while maintaining the sensitivity, durability and workflow compatibility required for scientific work. The goal is not to ask researchers to choose between performance and environmental responsibility, but to provide a membrane designed to deliver both.
The environmental challenge associated with laboratory consumables is increasingly important. Research depends on reliable single-use products, yet laboratories, institutions and suppliers are also looking for realistic ways to reduce persistent materials and improve the sustainability of scientific operations. Western blot membranes represent a small component of laboratory waste, but they are used globally and are essential to a widely established analytical method. VerdiBlot addresses this specific material category with a purpose-designed membrane that can be adopted through normal product evaluation. By improving one familiar consumable, laboratories can take a practical step toward more responsible research without replacing their instruments or abandoning established methods.

Manufactured by LAM-X in the European Union
VerdiBlot is manufactured by LAM-X a.s., a Czech technology company focused on advanced functional materials for life-science and other demanding applications. LAM-X combines material development, product engineering and manufacturing expertise to transform new material concepts into practical products. VerdiBlot is the result of this approach: a membrane created around the real requirements of Western blotting rather than a generic material adapted without regard to laboratory workflows. Manufacturing in the Czech Republic keeps product development close to production and allows feedback from researchers to inform ongoing technical support and future development.
European manufacturing is an important part of the VerdiBlot offer. Laboratories and distributors can work directly with the company responsible for the product, receive technical information and discuss evaluation results with a team that understands both the membrane and its intended application. Direct communication helps LAM-X respond to questions about transfer conditions, membrane handling, detection, stripping and troubleshooting. It also supports closer collaboration with research groups that want to test VerdiBlot in specific workflows or contribute practical observations. This relationship between manufacturer and user is especially valuable when introducing a new laboratory material, because successful adoption depends on both product quality and responsive technical support.

For researchers, laboratories and sustainability teams
For academic researchers, VerdiBlot provides a way to explore a new membrane technology without leaving the familiar Western blot format. It can support routine protein detection, pathway studies, antibody validation, multiplex experiments and repeated probing of valuable samples. For clinical and translational research teams, sensitivity and protein retention can be particularly important when working with scarce human material or low sample loads. For biotechnology and pharmaceutical laboratories, the membrane can be evaluated in research, assay-development and protein-characterization workflows. In every setting, the recommended approach is to compare VerdiBlot with the current membrane under matched experimental conditions and optimize only where necessary.
For laboratory managers and sustainability teams, VerdiBlot connects an environmental objective with a practical purchasing decision. A laboratory does not need to create a new analytical platform to begin reducing its use of persistent fluorinated materials. It can start by evaluating a consumable already used in routine work. Because VerdiBlot is designed to fit established transfer and detection workflows, scientific users can assess performance while procurement and sustainability stakeholders consider material composition, European manufacturing and long-term supply. This makes the membrane relevant not only to individual scientists but also to institutions developing responsible-laboratory policies.

For distributors and commercial partners
For distributors, VerdiBlot offers a differentiated Western blot product from a direct European manufacturer. The Western blot membrane market has long been dominated by conventional PVDF and nitrocellulose products, leaving limited room for meaningful material innovation. VerdiBlot introduces a distinct proposition built around sensitive detection, very low background, workflow compatibility, PFAS-free composition and 100% biodegradability. Distributors can offer customers a new option that addresses both scientific requirements and growing interest in more sustainable laboratory consumables. LAM-X supports partners with product knowledge, evaluation materials and direct communication so they can introduce the membrane responsibly and accurately.

Evaluate VerdiBlot side by side
The most effective way to evaluate VerdiBlot is through a side-by-side comparison with the membrane already used in the laboratory. Researchers can keep their samples, antibodies, buffers, transfer equipment and detection method consistent, allowing them to observe differences relevant to their own work. Useful comparison points include transfer quality, target signal, background, band clarity, handling, multiplex performance and the ability to strip and reprobe. This approach avoids relying only on general claims and gives each laboratory evidence grounded in its actual application. LAM-X welcomes feedback from both successful tests and workflows that require optimization because practical experience helps improve technical guidance.
VerdiBlot can be used with standard blocking agents and common total-protein staining methods. It is compatible with routine chemiluminescent, fluorescent and colorimetric detection approaches, giving laboratories flexibility in how transferred proteins are visualized. Researchers can continue using familiar antibodies and imaging platforms while assessing whether VerdiBlot improves the balance between signal and background in their particular assay. When optimization is needed, standard Western blot variables remain relevant: membrane wetting, transfer time, current or voltage, cooling, buffer composition, blocking conditions, antibody concentration, washing and exposure. LAM-X can help users review these variables and identify practical adjustments.
In transfer workflows, correct wetting and uniform contact are essential for every membrane. VerdiBlot normally equilibrates directly in an alcohol-containing transfer buffer and does not need the separate methanol pre-activation commonly associated with PVDF. Wet transfer can be particularly useful for high-molecular-weight proteins or experiments requiring longer transfer times, while semi-dry and dry systems can provide speed and convenience for routine work. The appropriate settings depend on the gel, protein size, buffer and equipment. VerdiBlot is therefore positioned as a flexible membrane platform rather than a single rigid protocol, enabling laboratories to integrate it into the transfer method that best fits their application.
Very low background is more than a visual advantage. Cleaner images can make it easier to distinguish weak bands, evaluate specificity and communicate results. In multiplex fluorescence, background reduction can improve contrast across channels. In chemiluminescence, it can help researchers select useful exposure times and interpret bands that might otherwise be obscured by non-specific signal. Background still depends on the complete assay, so blocking, antibody dilution, washing and exposure remain important. VerdiBlot provides a strong foundation, while good laboratory practice ensures that the membrane’s capabilities are translated into reliable experimental outcomes.
Stripping and reprobing extend the value of a transferred sample. A single blot may be used to examine a target protein, a pathway marker and one or more controls, reducing the need to repeat electrophoresis and transfer. This can save sample, reagents and working time while preserving comparability between targets measured on the same membrane. VerdiBlot is designed to tolerate repeated handling under appropriate conditions. Gentle stripping should be used first, with stronger conditions introduced only when necessary, because all stripping procedures can affect retained protein depending on the target and protocol. This balanced guidance helps laboratories use the membrane effectively without making unrealistic promises.
Collaboration with the scientific community
LAM-X sees VerdiBlot as both a product and a platform for collaboration with the scientific community. Feedback from researchers is essential because Western blotting covers a wide range of proteins, sample types, transfer systems and detection methods. Each new application adds practical knowledge that can help other users. LAM-X is interested in working with laboratories that want to evaluate specific targets, document workflows, share technical observations or prepare application-based evidence. Collaboration is approached with scientific care: results should reflect the conditions tested, comparisons should remain transparent and conclusions should not be extended beyond the available evidence.
VerdiBlot represents a new choice in a familiar method. It allows researchers to continue using Western blotting while considering a membrane that is PFAS-free, 100% biodegradable and manufactured in the European Union. It offers sensitive detection, very low background, support for multiplexing and the durability needed for staining, stripping and reprobing. It fits wet, semi-dry and dry transfer approaches and is compatible with widely used detection methods. Most importantly, it is designed to be tested in real laboratory conditions, where its value can be judged by the scientists who will use it.
