General description

Chymotrypsin, a serine protease, is frequently used in proteomics and protein analysis due to its highly specific enzymatic cleavage activity. As a USP reference standard, Chymotrypsin is used to validate enzymatic digestion procedures, assess protein conformation, and support structural elucidation studies in therapeutic protein development. This reference ensures that chymotrypsin activity remains consistent, reproducible, and compliant with analytical specifications.

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.
