Derived impurity
WebNational Center for Biotechnology Information WebSep 1, 2010 · A common problem with Protein A resins is non-specific binding of impurities such as host cell protein, DNA and other cell culture-derived impurities. The level of impurities bound depends on the resin, the composition of harvested cell culture fluid and column loading and washing conditions.
