Abstract
Host cell residual DNA is DNA fragment from host cells that may exist in biological products. Host cell residual DNA in biological products produced by passage cell lines may carry tumor or virus-related genes and has potential risks. Thus, drug regulatory agencies in various countries have strict limits on host cell DNA residual amounts, and pharmacopoeias of various countries have provided several classic detecting methods. Establishing appropriate methods for detecting residual DNA of host cells can help monitor the production process and ensure the safety and quality of biological products. This article reviews the potential risks of host cell residual DNA, standards and testing methods of host cell residual DNA from domestic and foreign regulatory agencies, and the characteristics of each method and its research progress.
Key words:
