Enzo Life Sciences E. coli host cell protein ELISA kit

Host cell proteins (HCPs) are a residual contaminant that can appear in the production of a biologic. HCPs are produced by organisms as a side product to the intended protein. While some are necessary for natural cellular functions, other HCPs are unnecessary and are merely carried through the process. Even though some may be completely harmless, it is generally undesirable to have HCPs in the final product.

The Enzo Life Sciences E. coli host cell protein ELISA kit is a sensitive ELISA for the quantitative determination of host cell protein contamination in bulk products expressed in E. coli expression systems. Advantages include: sensitive measurement of E. coli host cell protein, detecting as little as 30 ng/mL; high-throughput format with results in 3 h; and fully quantitative results that surpass semi-quantitative Western blot analysis, according to the company.
