Scientific Background
This multifunctional protein catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. May therefore cause structural modifications of exofacial proteins.
Product Description
E. coli ExpressionRecombinant Human Protein disulfide-isomerase protein (P4HB), partial (Active) is a recombinant protein expressed in E. coli and purified to >95% as determined by SDS-PAGE. as determined by SDS-PAGE. Supplied as Lyophilized powder, n-terminal 6xhis-tagged. For research use only.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Functional Activity
Biologically Validated
Thiol Protein Reductase Activity is 0.001 Δ650nm/ min-2, determined by measuring the turbidity increase at 650 nm due to insulin reduction.The activity is expressed as the ratio of the slope of a linear part of the turbidity curve to the lag time.
