In comparison, for your human and primate cell traces, the producing operators or cell line itself ended up suspected being the source. The reality that operators are only indicated to be a source in the contaminant in human or primate cell society and never in CHO mobile tradition is likely a result of the ‘species barrier’ for viral infection in between human or primate cells over the a single hand and rodent cells on the other. To put it simply, viruses that infect humans are more likely to have the option to duplicate in human cells than in non-human mammalian cells.
