CHO K1 ATCC cells—sourced from the American Type Culture Collection (ATCC)—are widely adopted in the manufacture of therapeutic proteins, monoclonal antibodies (mAbs), vaccines, and other biologics due to their robust growth characteristics, regulatory acceptance, adaptability to serumfree and chemically defined media, and ability to produce complex posttranslational modifications. https://www.databridgemarketresearch.com/reports/global-chinese-hamster-ovary-cho-k1-atcc-cells-market
