Peptidase Inhibitor 3, also referred to PI3, is neutrophil and pancreatic elastase-specific inhibitor of skin. The protein may prevent elastase mediated tissue proteolysis. PI3 has shown inhibition of alpha-4-beta-2/CHRNA2-CHRNB2 nicotinic acetylcholine receptor, a weak inhibition on Kv11.1/KCNH2/ERG1 and on the transient receptor potential cation channel subfamily V member 1.
PI3 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 101 amino acids (23-117a.a) and having a molecular mass of 10.7kDa.
PI3 is fused to an 6 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
The PI3 solution (0.2mg/ml) contains Phosphate-Buffered Saline (pH 7.4) and 10% glycerol.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 85.0% as determined by SDS-PAGE.
