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.

NF[kappa]B transcription factor assay kits
Supplier: Rockland Immunochemicals
These assays are non-radioactive methods for detecting specific transcription factor DNA binding activity in nuclear extracts and whole cell lysates. A specific dsDNA sequence containing the NF[kappa]B response element is immobilized on the bottom of the wells in a 96-well plate. The transcription factor is detected by the addition of a specific primary antibody. A colorimetric readout at 450 nm is obtained through a horseradish peroxidase-conjugated secondary antibody.

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.

Cell viability assay kits
Supplier: Biotium
MTT, XTT, and resazurin are reduced by mitochondrial metabolic activity to yield coloured or fluorescent products, and thus are useful for and assaying cell viability and quantitating cell number. MTT and XTT are reduced to coloured formazin salts that can be measured by absorbance. MTT generates an insoluble formazin salt, requiring cell lysis before the absorbance can be measured, while XTT does not require cell lysis for measurement. Resazurin is a non-fluorescent blue dye that is reduced to the pink fluorescent compound resorufin, which can be measured by fluorescence or absorbance.
