SensoLyte® 520 Cathepsin G Assay Kit

Catalog No. ABIN1882442

Quick Overview for SensoLyte® 520 Cathepsin G Assay Kit (ABIN1882442)

Target: Cathepsin G (CTSG)

Detection Method: Fluorometric

Application: Fluorescence Resonance Energy Transfer Microscopy (FRET)

Product Details

Brand: SensoLyte®

Characteristics: The SensoLyte® 520 Cathepsin G Activity Assay Kit uses a HiLyte Fluor™ 488/QXL™ 520 FRET peptide substrate for the measurement of enzyme activity. In the intact FRET peptide, the fluorescence of HiLyte Fluor™ 488 is quenched by QXL™ 520. Upon cleavage of the FRET peptide by the active enzyme, the increase of fluorescence can be continuously monitored at excitation/emission = 490/520 nm. With superior fluorescence quantum yield and longer emission wavelength, the HiLyte Fluor™ 488/QXL™ 520 based FRET peptide has less interference from the autofluorescence of test compounds and cellular components and provides better assay sensitivity. The fluorescent signal from HiLyte Fluor™ 488 is stable at low pH, which is the optimal pH for cathepsin activity. The kit can be used to detect the activity of Cathepsin G enzyme in biological samples and purified enzyme preparations.

Target Details

Target: Cathepsin G (CTSG)

Alternative Name: Cathepsin G

Background: Cathepsins are a class of globular lysosomal proteases playing a vital role in mammalian cellular turnover. They degrade polypeptides and are distinguished by their substrate specificities. Cathepsin G is the serine protease released by neutrophils upon their activation. Cathepsin G is currently being explored as a target for anti-inflammatory and anti-infective drugs.
