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.
Cyclic-GMP fluorescent assay kits, CatchPoint™
Supplier: Molecular Devices
CatchPoint™ cGMP Fluorescent Assay Kits measure cGMP levels via a competitive immunoassay format. The second messenger cyclic GMP (cGMP) modulates cellular processes, including smooth muscle relaxation, kidney function, and inflammation, by activating effectors such as protein kinases, cGMP-dependent phosphodiesterases, and cGMP-gated ion channels.

Protein quantitation assay kits, CB™ Protein assay
Supplier: G-Biosciences
CB™ Protein Assay, a Coomassie dye based protein assay based on the Bradford Protein Assay, is suitable for the simple and rapid estimation of protein concentration. The binding of protein to the dye results in a colour change from brown to blue. The change in colour density is proportional to protein concentration. Protein estimation can be performed using as little as 0,5 µg protein.

Neutrophil/Monocyte Respiratory Burst Assay Kit
Supplier: Cayman Chemical
Neutrophil/Monocyte Respiratory Burst Assay Kit provides PMA, dihydrorhodamine 123, and additional reagents necessary for inducing and quantifying a respiratory burst response in neutrophils and monocytes by flow cytometry. The assay can be performed on whole blood or on cells in various types of cell culture media. Because the assay reagents are not species-specific, this assay can be used in any species or cell type capable of producing a NADPH oxidase-dependent respiratory burst response.

FLUOR DE LYS® HDAC6 fluorometric drug discovery kit
Supplier: ENZO LIFE SCIENCES
A Fluor-de-Lys® fluorescent assay system. The HDAC6 Fluorescent Activity Assay/Drug Discovery Kit is a complete assay system designed to measure the lysyl deacetylase activity of the recombinant human HDAC6 included in the kit. The kit is ideal for chemical library screening for candidate inhibitors or activators or kinetic assay of the enzyme under varying conditions. The Fluor de Lys® HDAC6 assay is based on the Fluor de Lys® Substrate and Fluor de Lys® Developer combination. The assay procedure has two steps. First, the Fluor de Lys® Substrate, which comprises an acetylated lysine side chain, is incubated with HDAC6. Deacetylation of the substrate sensitizes the substrate so that, in the second step, treatment with the Fluor de Lys®Developer produces a fluorophore.

Protease Estimation Assay Kit, ProteSEEKER™
Supplier: G-Biosciences
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.
