Produktnummer ABIN1882436

Kurzübersicht für SensoLyte® 520 Cathepsin B Assay Kit (ABIN1882436)

Target: Cathepsin B (CTSB)

Nachweismethode: Fluorometric

Applikation: Fluorescence Resonance Energy Transfer Microscopy (FRET)

Produktdetails

Marke: SensoLyte®

Produktmerkmale: The SensoLyte® 520 Cathepsin B Activity Assay Kit provides a QXL™ 520/HiLyte FluorTM 488 labeled FRET peptide substrate for measurement of enzyme activity. In the intact FRET peptide, the fluorescence of HiLyte FluorTM 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 nm/520 nm. With superior fluorescence quantum yield and longer emission wavelength, the QXL™ 520/HiLyte FluorTM 488 based FRET peptide has less interference from the autofluorescence of test compounds and cellular components and provides better assay sensitivity.

Hintergrund: 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 B is a member of the cathepsin family consisting of 12 cysteine proteases with broad exo- and endopeptidase activity. Elevated levels of cathepsin B were detected in metastases and neurological disorders including Alzheimer's disease (AD).
