Cathepsin D (CatD) Activity Fluorometric Assay Kit

Cathepsin D (CatD) is an important intracellular aspartic acid protease and is widely present in the biological world. Cathepsin D has multiple biological functions and is involved in intracellular protein degradation, apoptosis and autophagy, etc. The detection principle of this kit: CatD hydrolyzes the substrate to generate the chromogenic substance. The activity of cathepsin D in the sample is calculated by measuring the changes in fluorescence values at the excitation wavelength of 328 nm and the emission wavelength of 393 nm
