HRV 3C Protease

Description

Description:
HRV 3C Protease is fused to GST, so that the protease is easily removed from cleavage reactions using immobilized glutathione (GSH). HRV 3C Protease is highly active at 4^oC, and also active in a variety of commonly used buffers, providing more flexibility in experimental design to keep the activity and intact structure of the target proteins.

Application:
HRV 3C Protease is a recombinant cysteine protease used to remove fusion tags from proteins with the HRV 3C cleavage sequence. HRV 3C Protease is highly specific for the PreScission Site, Leu-Glu-Val-Leu-Phe-Gln-↓-Gly-Pro, and cleaves between the Gln and Gly residues.

Figure. SDS-PAGE Analysis of Cleavage of Control Protein by HRV 3C Protease
A 66 kD GST-fusion protein (1) at 1 mg/ml is reacted with HRV 3C Protease at a ratio of 1: 100 (w/w) in cleavage buffer at 4°C for 4 hours (2) and 3 days (3). The cleaved products are 40 kD and 26 kD.
