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.

Compat-Able™ BCA™ Protein assay kit
Supplier: Thermo Fisher Scientific
The Compat-Able™ Reagents remove salts, detergents, reducing agents and other substances from protein samples to eliminate interference with protein assays. The protocol selectively precipitates all of the protein, thereby allowing the non-protein components to be easily decanted and removed. The purified, precipitated protein is redissolved in water, making it ready for accurate determination of the protein concentration by standard protein assay methods. The procedure is accomplished in less than 10 min with just a few simple steps. The Compat-Able™ Preparation Set is available conveniently bundled with the Pierce BCA™ Protein Assay Kit.

Fluorescent nerve terminal probes and stains
Supplier: Biotium
Nerve terminal probes are a series of fluorescent cationic styryl dyes developed to follow synaptic activity. These dyes have a lipophilic tail at one end and a hydrophilic cationically charged head group at the other end. The dyes vary in the number of carbons in the lipophilic tail (m) and the number of double bonds linking the two aromatic rings in the dye (n). AM dyes are similar to FM dyes, but contain an additional formaldehyde-fixable amino group in the cationic head.

FLUOR DE LYS® HDAC8 fluorometric drug discovery kit
Supplier: Enzo Life Sciences
A Fluor-de-Lys® fluorescent assay system. The HDAC8 Fluorescent Activity Assay/Drug Discovery Kit is a complete assay system designed to measure the lysyl deacetylase activity of the recombinant human HDAC8 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® HDAC8 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.

ADAM17 fluorometric drug discovery kit
Supplier: Enzo Life Sciences
Designed to screen ADAM17 (TACE) inhibitors using a quenched fluorogenic peptide. The ADAM17 Fluorometric (also known as fluorimetric) Drug Discovery Kit is a complete assay system designed to screen ADAM17 (TACE) inhibitors using a quenched fluorogenic peptide: Mca-PLAQAV-Dpa-RSSSR-NH2. Mca fluorescence is quenched by the Dpa group until cleavage by proteases separates the two moieties. The assays are performed in a convenient 96-well microplate format. The kit is useful to screen inhibitors of ADAM17, a potential therapeutic target. The compound GM6001 is also included as a prototypic control inhibitor.

β-Galactosidase Assay Kit and Reagents
Supplier: Thermo Fisher Scientific
The Mammalian β-Galactosidase Assay Reagent Kit is a simple and versatile assay to measure β-galactosidase activity in cultured mammalian cells. Cells grown on a plate may be lysed and tested for β-galactosidase activity by adding a single all-in-one lysis-and-assay solution. Alternatively, M-PER™ Mammalian Protein Extraction Reagent may be used to prepare lysate from washed adherent or pelleted cells, and then a portion of the lysate used to assay for β-galactosidase activity. With M-PER Reagent, there is no need to scrape cells or to perform freeze-thaw cycles. The remaining lysates prepared with M-PER™ Reagent may be used for applications such as reporter assays (luciferase, β-galactosidase and chloramphenical acetyltransferase), protein kinase assays (PKA, PKC, and tyrosine kinase), immunoassays (Western blot, ELISA, RIA) and protein purification.
