Product Name: hCG Protein

Product No: HOR-250

Synonym(s): Chorionic Gonadotropin Human, Chorionic gonadotropin, hCG, CG.

Description: Human Chorionic Gonadotropin is produced from a sterile preparation of placental glucoprotein urine of pregnant women having a total molecular mass of 36,700 Dalton. The hCG consists of 237 amino acids, a chain-92 amino acids and b chain-145 amino acids. The hCG is purified by proprietary chromatographic techniques.

Protein Derived From: Urine of pregnant women.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Stability: Lyophilized hCG although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CG-beta 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.

Biological Activity: The activity was found to be 6098U/mg.

Solubility: It is recommended to reconstitute the lyophilized Human Chorionic Gonadotropin in sterile 18MOmega-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.

Contaminants: Free of: HbsAg and antibodies to HIV and HCV.
