As we all know, biological agents are the fastest growing field in the pharmaceutical industry.In 2019, seven of the top ten best-selling drugs in the world are biological agents.Biological products include recombinant proteins, vaccines, and specific monoclonal antibodies.Related studies have shown that the rDNA of host cells in biological products has potential oncogenic and infectious risks.It may also cause gene insertion mutation, so detection of rDNA content is related to the quality and purity of biological products, and is an important indicator of product quality and safety.

Forensic DNA extraction kits (silicon bead method and magnetic bead method) developed by Shanghai Genebio has reached a considerable level.Forensic DNA extraction kits are biased towards factors such as anti-interference, anti-inhibition, trace,etc.While cellular residual DNA extraction kits focus on factors such as high sensitivity, high recovery,etc.At the same time, Shanghai Genebio also has matching domestic automatic extraction workstation, which can be used to compile corresponding extraction program according to different kits.
