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-AMP fluorescent assay kits, CatchPoint™
Supplier: Molecular Devices
CatchPoint™ cAMP Fluorescent Assay Kit measures cAMP levels via a competitive immunoassay format. Cell signaling via G protein-coupled receptors (GPCRs) can be assessed by monitoring the downstream effectors calcium or Cyclic AMP (cAMP). Monitoring levels of cAMP, a second messenger produced in response to activation of adenylate cyclase, is one of the most common ways to screen for agonists and antagonists of GPCRs.

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.

Peroxide assay kit, PEROXsay™
Supplier: G-Biosciences
PEROXsay™ is a colorimetric quantitative peroxide assay that measures the oxidation of ferrous (Fe²⁺+) ions to ferric (Fe³⁺) ions. Peroxides react with a sugar alcohol converting it to a peroxyl radical that subsequently starts the oxidation of ferrous ions to ferric ions. The acidic pH of the assay allows the ferric (Fe³⁺) ion to complex with the colorimetric reagent, resulting in a change in absorbance that is proportional to the peroxide concentration.
