CHO HCP 3G Assay Reagent Set for Gyrolab®, CD5 is designed for determining the presence of host cell protein contamination in products manufactured by expression in CHO cell lines. This Reagent Set should be used in conjunction with a Gyrolab® Bioaffy™ 1000 HC Assay Toolbox CD50 available from Gyros Protein Technologies. This simple to use, high throughput, and semi-quantitative assay is a method to aid in optimal purification process development, process control, routine quality control and product lot release. It is derived from the same antibodies and antigen used in the Cygnus 3rd Generation CHO HCP ELISA Kit, Cat# F550-1 The reagents are "generic” in the sense that they are intended to react with essentially all the host cell proteins (HCPs) that could contaminate the product independent of the purification process. The antibodies have been generated in goats and antigen affinity purified using CHO HCPs found in protein free conditioned media. The combination of the Reagent Set and Bioaffy 1000 HC Assay Toolbox CD50 s optimized for use in Gyrolab automated immunoassay systems enabling generation of 96 data points in 75 minutes without manual intervention. The results are evaluated using Gyrolab Evaluator software.
