WebEP 2.6.34 host-cell protein assays Validation • Accuracy, Specificity, Precision, Range and Robustness: – As for any other quantitative assay • Quantitation and detection limits – ppm range – quantitation limit determined – Detection limit (DL): often not determined • Linearity – dilution non-linearity to be assessed WebAn Effective SWATH-MS Workflow for the Analysis of CHO HCPs. Speaker: Xuezhi Bi, Bioprocessing Technology Institute, A*STAR Abstract: Residual host cell proteins (HCPs) impurity is one of the critical quality attributes (CQAs) in CHO-produced biotherapeutic monoclonal antibodies (mAbs). In order to monitor individual CHO HCP clearance, a …

WebThe major factor limiting the application of MS in the detection of downstream HCPs is sensitivity and specificity. In most well purified products HCP content will be composed of numerous individual HCPs that in total are less than 100 ppm. MS discrimination of the drug substances at mg/mL from individual HCP at low ppm levels is problematic. WebCell lines from multicellular organisms like HEK293 or CHO cells usually require complex rich media, including amino acids, vitamins, and growth factors in contrast P. pastoris can grow in media containing only one carbon source and one nitrogen source, further reducing production costs. 3 P. pastoris is not sensitive to pH changes, the yeast ...
