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.

Omschrijving: Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF™594 to stain the surface of gram-positive cells with red fluorescence. The kit also includes DAPI to stain the DNA of all bacteria with blue fluorescence. Gram-positive bacteria stained using this kit will show a fluorescent blue interior and fluorescent red cell surface, while gram-negative bacterial will be stained with blue fluorescence only.

Omschrijving: The oligomeric form of Amyloid Beta peptide (Aβ, 1- 42) has been closely linked to Alzheimer’s Disease. Several ELISAs targeting Aβ have been developed; however, these ELISAs are known to cross-react with Amyloid Beta precursor protein (APP) and are poorly characterised against monomeric and oligomeric forms of the peptide.

Leverancier: Biosensis
Omschrijving: The Biosensis GDNF RapidTM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of GDNF in less than 4 hours in cell culture supernatants, cell lysates, and serum only if used as directed.
