• In June 2022, Evonik launched cQrex AC, a highly pure and soluble cystine peptide, to enhance cell culture media used in biopharmaceutical production. This new addition to the company’s cQrex portfolio addresses the challenge of delivering enough cysteine, an essential amino acid, to cells. cQrex AC is non-animal-derived, chemically defined, and has over 20 times greater solubility than L-cystine at a neutral pH. The cQrex AC is very similar to cQrex KC launched in 2023 but it is lower in solubility than cQrex.
