Human Chorionic Gonadotropin is produced from a sterile preparation of placental glucoprotein urine of pregnant women having a total molecular mass of 36.7 kDa. 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.
Synonyms: Chorionic gonadotropin, hCG, CG.
Formulation: The hCG was lyophilized with no additives.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Source: Urine of pregnant women.
Transportation method: Shipped at room temperature.
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 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
