| Chorionic Gonadotropin Human, hCG, 5mg|
The activity was found to be 5000 IU/mg.
Free of: HbsAg, Hepatitis B surface antigen and antibodies to HIV, Hepatitis C and HCV.
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.
The hCG was lyophilized with no additives.
Sterile Filtered White lyophilized (freeze-dried) powder.
Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 1.06 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of hCG as a Reference Standard.
Purity is 98%.

It is recommended to reconstitute the lyophilized Human Chorionic Gonadotropin in sterile 18M¦¸-cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
Urine of pregnant women.
Lyophilized hCG although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution CG-beta should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
