D25.4x1mm Multi-Wavelength Enzyme Label Filter

340nm 380nm 405nm 450nm 505nm Band Pass Filter Enzyme Label Filter In clinical laboratory tests, enzyme - labeled filter sheets of different wavelengths are widely used in the detection of various disease diagnostic markers. For example, 340nm filter sheets are often used for enzyme - based assays based on NADH/NAD+ redox reactions, such as lactate dehydrogenase (LDH), which can be used to assess cell damage and tissue necrosis. 405nm and 450nm filter sheets are extensively used in enzyme - linked immunosorbent assay (ELISA) to detect tumor markers (such as carcinoembryonic antigen CEA), cardiovascular disease markers (such as troponin TnI) and infectious disease pathogens (such as hepatitis B virus HBV antigen), providing an important basis for early disease diagnosis, disease monitoring and treatment evaluation.In drug screening and pharmacological research, enzyme - labeled filter sheets can be used to detect cell viability, cell proliferation, cell toxicity, and the interacti…
