Our Abpromise guarantee covers the use of ab157275 in the following tested applications.
Substrate recognition and cleavage are likely to be dependent not only upon primary structural signals, but also upon the secondary and tertiary structures of the fusion protein as It has been demonstrated that the enzyme exhibits highest activity around neutral pH at temperature ranging from 22 to 37°C, even retaining robust activity at 4°C. Thus, cleavage can be performed at low temperature to enhance the stability of the target protein. The catalytic activity is insensitive to organic solvents (up to 10%); however, it can be strongly stimulated by high concentration of anions such as sulfate.The high specificity of ab157275 makes it an ideal tool for cleaving fusion proteins at definite cleavage sites. The enzyme recognizes the cleavage site: Leu-Glu-Val-Leu-Phe-Gln-Gly-Pro. >1 Units/µg. One unit will cleave >95% of 100 µg control fusion protein in 50 mM Tris-HCl, 150 mM NaCl, pH 7.5 at 4°C for 16 h.
