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 behaviour than what can be handled by traditional chemical analysis and titration.

Multi-Neurotrophin Rapid™ screening ELISA kit: Rat

Catalog Number: (BSENBEK-2232)
Supplier: Biosensis
Description: The Biosensis Multi-Neurotrophin Rapid™ Screening ELISA Kit has been designed to allow rapid screening and quantification of NGF, BDNF, NT3 and NT4/5 in cell culture supernatants, lysates, serum and brain extracts only if used as directed.
UOM: 1 * 192 Tests
Product Image-786-320

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.
