Chorionic Gonadotropin alpha Chain (hCG alpha) Native Protein Summary

Description
Native bioactive protein containing amino acids for Human hCG Alpha (Intact)

Source:Urine of post-menopausal women

This product is manufactured by Abcam and distributed by Novus Biologicals. (Abcam Catalog Number: ab51782)
Preparation
Method
Determined to be >98% pure by SDS-PAGE
Details of Functionality
hCG is biologically active compared to standard. The biological activity of hCG is determined by using the seminal vesicle weight gain test in male rats described in the "Chorionic Gonadotrophins" monograph of the European Pharmacopoeia. The in vivo biological activity of hCG has been calibrated against the third international reference preparation IS75/587 for chorionic gonadotropin. The specific activity was found to be 5000 IU/mg.
