Description

General description

Find answers to frequently asked questions on USP products in USP FAQs.

Human chorionic gonadotropin (hCG) is a glycoprotein hormone produced by the placenta, used therapeutically for reproductive hormone regulation. The USP reference standard supports potency assays, identity testing, and bioassay calibration for hCG drug substances.

The USP biologics proteins category provides critical standards and reference materials necessary for the development and manufacturing of therapeutic proteins. These proteins, which can be naturally derived or genetically engineered, are essential in treating various diseases and conditions, ensuring that they meet quality, safety, and efficacy standards.

The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.

Glycoprotein hormone consisting of a 92-amino acid α-chain which is identical to that of LH, FSH, and TSH; and a distinct 149-amino acid β-chain. Produced by chorionic tissue and responsible for maintaining the corpus luteum during early pregnancy. Also produced by trophoblast cell neoplasms, which are marked by elevated free hCG β-chains and hyperglycosylated hCG.
