The Fluorogenic Prolyl OligoPeptidase (POP) Assay Kit is a complete assay system designed to measure activity of the purified POP enzyme. The Fluorogenic POP Activity Kit eliminates the dealing with radioactive materials and chromatography in traditional assays. Purified human recombinant POP is included in the kit as a positive control. Using this kit, only one simple step, in which the fluorometric substrate is incubated with purified POP, is needed to analyze the POPactivity level. The resulting fluorescent product can then be easily measured with a microtiter-plate fluorimeter.
