Description

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.

ELISA is a simple, highly sensitive and objective method for detecting HCPs. This kit uses the experimental principle of double-antibody sandwich enzyme-linked immunoassay (ELISA) to detect the residual amount of E.coli HCP. To detect E.coli HCP residues, add the E.coli HCP standard and the sample to be tested to the enzyme label pre-coated with anti-E.coli HCP antibody plate (36712-A). Then add diluted biotin-labeled E.coli HCP detection antibody (36712-C), and finally add Streptavidin-HRP (SA-HRP) (36712-D) to form antibody+antigen+antibody ‐Biotin+ SA‐HRP complex. After washing the plate, add TMB color developing solution (36712-G) to develop color. TMB was transformed from colorless to blue under the catalysis of HRP enzyme and finally transformed into yellow under the action of stop solution (36712-H). The shade of yellow is positively correlated with the amount of E.coli HCP detected in the sample. This kit can be used for optimizing the purification process of biological products, controlling impurities in the intermediate process, and detecting the release of final products.
