Protease Serine 7, also known as PRSS7, is in charge of initiating the activation of pancreatic proteolytic proenzymes such as trypsin, chymotrypsin and carboxypeptidase A. PRSS7 catalyzes the conversion of trypsinogen to trypsin which in turn activates other proenzymes including chymotrypsinogen, procarboxypeptidases, as well as proelastases.
PRSS7 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 237 amino acids (785-1019 a.a.) and having a molecular mass of 26.4kDa. The PRSS7 is purified by proprietary chromatographic techniques.
Sterile filtered colorless solution.
The PRSS7 protein solution (1mg/ml) contains 20mM Tris-HCl buffer (pH8.0) and 10% glycerol.
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.
Greater than 85% as determined by SDS-PAGE.
