Hyperglycosylated human chorionic gonadotropin and human chorionic gonadotropin free beta-subunit: tumor markers and tumor promoters.

The Journal of reproductive medicine, 2008
Human chorionic gonadotropin (hCG) is a heterogeneous glycoprotein hormone comprising an alpha-subunit and beta-subunit that can vary in peptide and carbohydrate structure. After conception, hCG produced by early trophoblast cells acts on luteinizing hormone (LH)/hCG receptor corpus luteum cells to promote progesterone production and establish maternal

Identification and selective destruction of shared epitopes in human chorionic gonadotropin beta subunit

Journal of Reproductive Immunology, 1996
The feasibility of producing epitope-specific antigens by mutation of the gene is demonstrated, the aim being to eliminate unwanted surface epitopes yet allowing the natural folding of the protein to maintain the desired epitope(s). The model protein is the beta subunit of human chorionic gonadotropin (hCG beta) which previously has been used as an ...

SYNTHESIS OF CARBOXYL TERMINAL SEGMENTS OF BETA‐SUBUNIT OF HUMAN CHORIONIC GONADOTROPIN

International Journal of Peptide and Protein Research, 1980
The synthesis in solution of carboxyl terminal peptide segments of the beta‐subunit of human chorionic gonadotropin is described. The protected segments include sequences 119–131, 132–137, and 138–145. The syntheses were based on a standardized liquid‐liquid extraction program for routine purification of intermediates (two‐phase method).
