E.coli HCP ELISA kit

Recombinant expression in Escherichia coli is a relatively simple and cost-effective means of producing some proteins and plasmid DNA. During the process of product production using Escherichia coli, there is a high possibility of contamination of host cell proteins (HCPs) from Escherichia coli, which may reduce the efficacy of therapeutic drugs and cause adverse toxicity or immune responses. Therefore, during the production and purification of therapeutic drugs for humans or animals, it is necessary to minimize the content of this impurity as much as possible.
