PI3 is an elastase-specific protease inhibitor, which contains a WAP-type four-disulfide core (WFDC) domain, and is thus a member of the WFDC domain family. Most WFDC gene members are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. PI3 belongs to the centromeric cluster.
PI3 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 118 amino acids (23-117) and having a molecular mass of 12.0kDa.
PI3 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Sterile filtered colorless solution.
The PI3 solution contains 20mM Tris-HCl buffer (pH 8.0), 0.15M NaCl, 1mM DTT 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 80% as determined by SDS-PAGE.
