Keep drug development on schedule with confident assessment of CHO impurities.

CHO cells are great at producing monoclonal antibodies, but the process comes with plenty of impurities including host cell proteins (HCPs), genomic DNA (gDNA)

• Use our stable isotope labeled peptide Analytical Reference Materials (ARMs) with USP Chapter to identify and quantify HCPs like clusterin and lipoprotein lipase using a new mass spec-based method
• Use the CHO Genomic DNA RS with USP Chapter to assess the level of remaining gDNA.
• Use our purified recombinant CHO phospholipase B- like 2 protein (PLBL2) to assess this problematic HCP.
