Recombinant Enterokinase

Recombinant Enterokinase is a kind of high purity recombinant bovine intestinal kinase. The enzyme is HPLC purified, its purity and specificity is high, it does not contain other protease. Enterokinase is a specific protease, which can cut lysine carboxy terminal site which has four aspartic acid in the front.

Activity:

≥10u/μl
≥50u/μl

Package:100U,1000U,bulk

Items	Content
Source	Recombinant Escherichia coli
Theoretical MW	MW：25,850DA
Enzyme activity	1U is defined as the enzyme amount needed for cutting 95% of 50ug fusion protein which preserved in 25mMTris-HCl8.0 buffer in 12h~16h at 25℃ temperature.
Storage	It should be stored under-20℃.
Stability	It can be transported at room temperature , it can be kept stably for a week at the temperature of 25℃, Enzyme liquid can be repeated freeze-thaw for times while the enzyme activity doesn’t be affected.

Recombinant Enterokinase can remove fusion protein located in protein N- terminal, so as to remove the unneeded fusion tags.

Product advantage:

High purity

High specificity: Specific protease, excluding other protease, no non-specific cutting
