Host-cell protein impurity analysis
WebHost cell proteins ( HCPs) are process-related protein impurities that are produced by the host organism during biotherapeutic manufacturing and production. During the purification process, a majority of produced HCPs are removed from the final product (>99% of impurities removed). WebHost cells are manipulated to express the protein of interest however they still pursue their normal endogenous expression pattern, resulting in a heterogeneous protein mixture. …
