Introduction
WELQut Protease is an extremely specific and recombinant serine protease from Staphylococcus aureus. The WELQut Protease identifies and accurately cleaves recombinant proteins that has a recognition sequence added to them, with the amino acid sequence Trp, Glu, Leu, Gln, X (any amino acid). WELQut Protease cut externally from the recognition sequence, therefor doesn’t leave extra amino acids bound to the target protein. The protease isn’t temperature sensitive (works in 4-30°C) or pH sensitive (pH 6.5-9.0), also, there is no need in any particular buffers.
Description
Welqut Protease Recombinant is a single, non-glycosylated polypeptide chain containing 204 amino acids and having a molecular mass of 22kDa. The Welqut Protease is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
Welqut Protease contains 10 mM Na2HPO4, 50% glycerol, 1.8 mM KH2PO4, pH 7.3, 140 mM NaCl and 2.7 mM KCl.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Avoid multiple freeze-thaw cycles.
Purity
Greater than 97.0% as determined by SDS-PAGE.
Unit Definition
Each unit is defined as the amount of enzyme required to cleave ≥99% of 100μg of a control protein in 16 h at 20°C. Enzyme activity is assayed in 100μl 100 mM Tris-HCl (pH 8.0).
