SensoLyte® 520 Calpain Activity Assay Kit

Catalog No. ABIN1882423

Product Details

Target: Calpain

Detection Method: Fluorometric

Application: Activation (Act), Fluorescence Resonance Energy Transfer Microscopy (FRET)

Brand: SensoLyte®

Characteristics: The SensoLyte® 520 Calpain Assay Kit is optimized for detecting calpain activity. This kit contains a novel internally quenched 5-FAM/QXL™ 520 FRET substrate. Calpain protease cleaves the FRET substrate into two separate fragments resulting in the release of 5-FAM fluorescence which can be monitored at excitation/emission= 490/520 nm. Increase in fluorescence is proportional to the calpain activity. The assay can detect both calpain 1 (µ) and 2 (m) activities and is ideal for kinetic study of these enzymes. The long wavelength fluorescence of 5-FAM is less interfered by the autofluorescence of components in biological samples and test compounds. The assays are performed in a convenient 96-well microplate format.

Background: The calpains are a family of intracellular Ca2+ dependent cysteine proteases. The best-characterized calpains are isoforms 1 (µ) and 2 (m). They respond to Ca2+ signals by cleaving many specific proteins, thereby irreversibly modifying their function(s). Calpains are implicated in a variety of Ca2+ regulated cellular processes as well as various pathological phenomena such as ischemic injury, muscular dystrophy, diabetes, cataract, atherosclerosis, Alzheimer's disease, and cancer. Calpains represent potential therapeutic targets for drug discovery.
