Welqut Protease, His

Source: Escherichia Coli. Sterile filtered colorless solution.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 doesnâ€TMt leave extra amino acids bound to the target protein. The protease isnâ€TMt temperature sensitive (works in 4-30°C) or pH sensitive (pH 6.5-9.0), also, there is no need in any particular buffers.Welqut Protease Recombinant is a single, non-glycosylated polypeptide chain containing 210 amino acids and having a molecular mass of 22kDa. The Welqut Protease is fused to a 6 amino acid His tag at C-terminus and is purified by proprietary chromatographic techniques.
