Having reached Stage 6 of the PDG process, General Chapter <1052> Biotechnology-Derived Articles—Amino Acid Analysis has been formally approved by the General Chapters—Biological Analysis Expert Committee in accordance with the Rules and Procedures of the 2015–2020 Council of Experts.
Changes from the existing USP–NF General Chapter include:
- In the Methods 6 and 7, the text stating that protein standard samples to be used for hydrolysis contain “1 to 8 mol of cysteine” was revised to “1 to 8 mol cysteine per mol protein”.
The <1052> Amino Acid Analysis General Chapter will be incorporated into and become official with the USP 41–NF 36.
