P4HB, Human

(P4Hbeta, PDI, PDIA1, PHD, PO4DB, PO4HB, ERBA2L.)

P4HB is a multifunctional and highly abundant enzyme that is part of the protein disulfide isomerase family. When present as a tetramer consisting of two alpha and two beta subunits, P4HB has a role in hydroxylation of prolyl residues in preprocollagen. P4HB is a disulfide isomerase containing two thioredoxin domains that catalyze the formation, breakage and rearrangement of disulfide bonds.

P4HB Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 512 amino acids (18-508 a.a.) and having a molecular mass of 57.5 kDa. The P4HB is fused to a 21 amino acid His Tag and purified by conventional chromatography.

Purity: Greater than 90.0% as determined by SDS-PAGE.

Source: Escherichia Coli.

Physical Appearance: Sterile Filtered colorless solution.

Formulation: The P4HB 1mg/ml protein solution contains 20mM Tris-HCl pH-8, and 10% glycerol.

Storage:
P4HB although stable 4°C for 4 weeks, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
