Recombinant humaan choriongonadotrofine subeenheid bèta/CGB-eiwit

CGB is a member of the glycoprotein hormone beta chain family and is the beta 3 subunit of chorionic gonadotropin (CG) . Glycoprotein hormones are heterodimers consisting of a common alpha subunit and an unique beta subunit which confers biological specificity. CG is produced by the trophoblastic cells of the placenta and stimulates the ovaries to synthesize the steroids that are essential for the maintenance of pregnancy. 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. Recombinant human CGB protein, fused to His-tag at N-terminus, was expressed in E. coli.
