You Searched For: Assays

An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behavior than what can be handled by traditional chemical analysis and titration.

Transferrin ELISA kit, Enzo Life Sciences

Catalog Number: (ENZOENZKIT1430001)
Supplier: ENZO LIFE SCIENCES
Description: Highly sensitive Transferrin ELISA kit enabling detection of transferrin in serum and plasma in just 2 hours.
UOM: 1 * 1 KIT
Product Image-786-325

Protease Estimation Assay Kit, ProteSEEKER™

Catalog Number: (786-325)
Supplier: G-Biosciences
Description: ProteSEEKER™ identifies specific types of proteases with a panel of twelve protease inhibitors and a sensitive colorimetric protease screening assay. ProteSEEKER™ allows researchers to screen their protein samples and establish which specific class of proteases are present and therefore design a highly specific protease inhibitor cocktail using the minimal number of protease inhibitors. Alternatively, ProteSEEKER™ can be used to test existing protease inhibitor cocktails and identify their inadequacies and therefore supplement in additional protease inhibitors.

Protein quantitation assay kits, Non-Interfering™ (NI™) Protein Assay

Catalog Number: (786-005)
Supplier: G-Biosciences
Description: A highly sensitive colorimetric protein assay that overcomes interference of common laboratory agents present in protein solutions and shows minimal protein-to-protein variation. The assay is unaffected by the presence of common laboratory agents such as reducing agents, chelating agents, detergents, amines, sugars, chaotropes, salts, drugs, antibiotics, cobalt, and others.
UOM: 1 * 1 KIT

Fluorescent protease assay, Fluoro™

Catalog Number: (786-320)
Supplier: G-Biosciences
Description: The Fluoro™ Protease Assay Kit is designed for the quantitative determination of proteases present in a protein sample. The assay uses fluorescein isothiocyanate (FITC)-labelled casein as a general protease substrate. The fluorescein label on the FITC-casein is highly quenched. When the proteases present in the sample of interest digest the FITC-casein substrate into smaller peptides, the quenching of the fluorescence label is relieved and the fluorescence of the substrate is increased. The fluorescence of the FITC-labeled peptide is measured with excitation at 485 nm and emission at 530 nm to determine protease activity. The kit detects picogram level of proteases present in the sample.

Brain-derived Neurotrophic Factor (BDNF) Rapid™ ELISA Kit (CE marked)

Supplier: Biosensis
Description: The Biosensis CE Marked BDNF Rapid™ enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the preferential quantification of mature BDNF in less than 3 hours. This kit consists of a pre-coated mouse monoclonal anti-BDNF capture antibody, a biotinylated anti-BDNF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3’,5,5’- tetramethylbenzidine, TMB) yields a coloured reaction product which is directly proportional to the concentration of BDNF present in samples and protein standards.
