Product overview
HRV 3C Protease Activity Assay Kit (Colorimetric) (ab211088) provides a convenient method for detecting HRV 3C Protease activity in mammalian tissue samples, biological fluids and from purified proteins. The assay kit is based on the ability of a 3C Protease (derived from a HRV rhinovirus-14) to cleave a chromogenic peptide substrate to release a chromophore (pNA) which can be easily quantified using a microplate reader. This assay kit is simple, rapid and can detect HRV 3C Protease activity from as low as 50 ng protein present in samples.

Notes
This product is manufactured by BioVision, an Abcam company and was previously called K214 HRV 3C Protease Activity Assay Kit (Colorimetric). K214-100 is the same size as the 100 test size of ab211088.
Human rhinovirus (HRV) infections are the most frequent causative agents of common cold and various other upper respiratory tract infections. Rhinoviruses are members of the picornavirus family, which have a positive-sense, single-stranded RNA genome that is translated into a single polyprotein precursor. In the case of HRVs, the viral polyprotein is mainly processed by the proteases (2A and 3C) to generate functional proteins and enzymes.
Human rhinovirus 3C protease (EC: 3.4.22.28) is a cysteine protease that recognizes the cleavage site Leu-Glu-Val-Leu-Phe-Gln*Gly-Pro.

Relevance
Human rhinovirus 3C protease (HRV3C Protease) is a cysteine protease that recognizes the cleavage site of Leu-Glu-Val-Leu-Phe-Gln-Gly-Pro. It cleaves between Gln and Gly (independent of Pro). (HRV) 3C Protease is used to remove fusion tags from proteins with the HRV 3C cleavage sequence and is typically dual tagged for easy removal from the sample after cleavage.
