Description:
SUMO (Small Ubiquitin-like MOdifiers) Protease is a highly purified Ulp1 from a E. coli expression system, which carries the yeast Ulp1. It recognizes the tertiary structure of SUMO and cleaves SUMO from recombinant fusion proteins. The SUMO protease has a N-terminal His-tag and can be removed by Ni-NTA agarose.

Applications:

• Removal of fusion tags from recombinant proteins
• Highly dynamic and precise cleavage capabilities
• Purification of proteins and peptides

Quality Control:
SUMO Protease has greater than 95% purity with no non-specific protease contamination. It is functionally tested for the absence of any non-specific protease activity.

Unit Definition:
One unit of SUMO Protease is defined as the amount of enzyme needed to cleave 85% of 2µg of substrate protein at 30°C in one hour.

Recommended Storage Condition: -80°C
