The Smart Solution for DNA Removal in Biopharmaceutical Production by Benzonase Endonuclease

Abstract

More and more mammalian cells especially continuous cell lines were used to produce vaccines and therapeutic biological products with the rapid development of biomedical technologies. Therefore, more attention should be paid from drug regulatory authorities to the safety of biological products especially quality control of residual DNA and RNA. World Health Organization has evaluated the methods commonly used in vaccine manufacture for their ability to reduce the biological activity of DNA. Benzonase endonuclease is frequently used during the production of vaccines and can degrade all nucleic acid sequences down to oligonucleotides of approximately 3 to 5 base pairs.
