Dsb proteins (DsbA, DsbB, DsbC, and DsbD) catalyze formation and isomerization of protein disulfide bonds in the periplasm of Escherichia coli. DsbC is periplasmic enzyme known as a disulfide isomerase and can convert aberrant disulfide bonds to correct ones. Disulfide-bond isomerase recombinant produced in e. coli is a single, non-glycosylated, polypeptide chain containing 216 amino acids (21-236) and having a molecular mass of 23.5 kda. dsbc is purified by proprietary chromatographic techniques. Applications: Western blot; elisa. Group: Enzymes. Synonyms: DsbC; Thiol:disulfide interchange protein dsbC. Purity: Greater than 95.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. DsbC. Mole weight: 23.5 kDa. Stability: Disulfide-Bond Isomerase Recombinant although stable at 4°C for 1 week, should be stored desiccated below -18°C. Please prevent freeze-thaw cycles. Appearance: Sterile filtered colorless solution. Source: E. coli. DsbC; Thiol:disulfide interchange protein dsbC. Cat No: NATE-0827.
DsbA appears to be necessary for correct formulation of disulfide bonds in exported proteins in vivo. DsbA is useful as a standard in immunoblotting. This protein catalyses the reduction and exchange of disulfide bonds and the oxidation of free sulfhydryl groups in vitro. It is the strongest oxidant of the thioredoxin superfamily. This thio/disulfide oxidoreductase is required for efficient disulfide bond formation in the periplasm of E. coli. Disulfide oxidoreductase produced in e. coli is a periplasmic protein isolated from e. coli, containing 208 amino acids having a molecular mass of 23,149 dalton. the dsba is purified by proprietary chromatographic techniques. Applications: Western blot. Group: Enzymes. Syno. Purity: Greater than 95.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. DsbA. Mole weight: 23,149 Da. Stability: Lyophilized DsbA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution DsbA should be stored at 4°C between 2-7 days and for future use 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. Appearance: Sterile Filtered White lyophilized (freeze-dried) powder. Source: E. coli. DsbA; Thiol:disulfide interchange protein dsbA; Disulfide Oxidoreductase. Cat No: NATE-0828.
