    摘要: The present invention provides a novel robust, sensitive, reproducible, and accurate method of detecting and quantifying host cell genomic DNA contamination utilizing quantitative real time Polymerase Chain Reaction (qPCR), wherein the qPCR primers are complementary to the highly repetitive host cell genomic DNA sequences, e.g., Alu-equivalent sequences. The present invention is particularly useful for determining the levels of residual genomic DNA in biological products to be administered as therapeutics, e.g., therapeutic proteins.
