Human Chorionic Gonadotrophin, beta subunit (purified) Reference standard

• Cat.No.: CGA-210H
• Product Overview: This product contains the beta subunit of human chorionic gonadotrophin, purified to remove other forms of human chorionic gonadotrophin, including nicked forms of hCG and its subunits.

Specification

• Description: This gene is a member of the glycoprotein hormone beta chain family and encodes 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.
• Species: Human
• Form: Lyophilised residue containing approximately 1.0 nmol purified human chorionic gonadotrophin-β, 2 mg human serum albumin, phosphate buffer salts (50mM pH7.4)
• Notes: The preparation contains material of human origin, and either the final product or the source materials, from which it is derived, have been tested and found negative for HBsAg, anti-HIV and HCV RNA. As with all materials of biological origin, this preparation should be regarded as potentially hazardous to health. It should be used and discarded according to your own laboratory's safety procedures. Such safety procedures should include the wearing of protective gloves and avoiding the generation of aerosols. Care should be exercised in opening ampoules or vials, to avoid cuts.
• Storage: Unopened ampoules should be stored at –20 centigrade.
