Chorionic Gonadotropin Beta Human Recombinant

Glycoprotein hormones are heterodimers consisting of a common alpha subunit and a unique beta subunit which confers biological specificity. CGB is a member of the glycoprotein hormone beta chain family and is the beta 3 subunit of (CG). CG is produced by the trophoblastic cells of the placenta and stimulates the ovaries. The beta subunit of CG is encoded by 6 genes which are arranged in tandem and inverted pairs on chromosome 19q13.3 and contiguous with the luteinizing hormone beta subunit gene.Description: CGB Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 168 amino acids (21-165 a.a.) and having a molecular mass of 17.9kDa. CGB is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.Physical Appearance: Sterile filtered colorless solution.Formulation: CGB protein solution (0.5mg/ml) containing 20mM Tris-HCl buffer (pH 8.0), 0.4M Urea and 10% glycerol.Stability: 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.Purity: Greater than 85.0% as determined by SDS-PAGE.
