E.coli HCP ELISA kit

This kit was developed using largely reactive polyclonal antibodies to the hundreds of different HCPs and is determined for use in establishing the presence of E.coli host cell protein contamination in products manufactured by recombinant expression. Polyclonal antibodies used in this kit have been generated against several strains of E. coli and specifically selected for their recognition of a large spectrum of E. coli proteins. Therefore, this kit can be regarded as generic and permits a relative-quantitative determination of HCP E. coli in many types of samples, such as samples issued from the purification process (HCP clearance), process control, quality control, or product release. Using this kit, HCP concentration is measured in ng/ml.
