INTERCHIM: Bioprocess impurities ELISA kits

Bioprocess impurities ELISA kits

Detection of leached Protein A, Protein G, BSA, anti-BSA or FCS and Host-Cell Proteins (HCPs) or anti-HCP… are considered as critical quality attributes (CQA) in industry and they have to be assessed prior to batch release.


The most popular method to acheive a sensitive detection is Immunoassays, started with ELISA (enzyme-linked immunosorbent assay) but other orthogonal methods (such as LC-MS) are appearing to help identifying individual HCPs and better understand their potential impacts. Please check below littérature describing analytical tool for HCP measurment.
