SensoLyte® 520 TACE ( α-Secretase) Activity Assay Kit *Fluorimetric* - ANA72085 - 1 kit - AnaSpec - assays & kits

TACE (tumor necrosis factor-alpha convertingEnzyme), α-secretase, or ADAM17 is a member of the ADAM family of proteases that contain both disintegrin and metalloprotease (catalytic) domains. ThisEnzyme is involved in sperm-egg binding and fusion, muscle cell fusion, neurogenesis, modulation of Notch receptor and ligand processing, and processing of the pro-inflammatoryCytokine, TNF α. TACE is currently being explored as a target for anti-inflammatory drugs. SensoLyte® 520 TACE Activity Assay Kit uses a 5-FAM (fluorophore) and QXL® 520 (quencher) labeled FRET peptide substrate for continuous measurement ofEnzyme activity. In the intact FRET peptide, the fluorescence of 5-FAM is quenched by QXL® 520. Upon cleavage of the FRET peptide by the activeEnzyme, the fluorescence of 5-FAM is recovered, and can be continuously monitored at excitation/emission = 490 nm/520 nm. With superior fluorescence quantum yield and longer emission wavelength, 5-FAM/QXL® 520 based FRET peptide has less interference from the autofluorescence of test compounds and cellular components and provides better assay sensitivity. The kit can be used to detect the activity of TACE or screen for TACE inhibitors. The assays are performed in a convenient 96-well format.
