Host Cell Impurity Testing

Host Cell Impurity Testing

Host cell proteins are the biggest protein contaminant in biopharmaceuticals that have been derived by recombinant DNA-technology, and they require protein recovery processes to minimize their content in a final product. They are also often immunogenic and pose risks to both the efficacy of a drug and patient safety. Host cell DNA levels are also a contaminant, and regulatory bodies such as the World Health Organization, the EU and the FDA have set maximum levels that they consider safe in products.
