Viral inactivation is to stop the viruses in a given sample from contaminating the desired product either by removing viruses completely or rendering them non-infectious. These techniques are used widely in the food and blood plasma industries, as those products can be harmed by the presence of viral particles. Some of the more common viruses removed by these methods are the HIV-1 and HIV-2 viruses; hepatitis A, B, and C; and parvoviruses. These methods have been adapt… WebBecause enzymes guide and regulate the metabolism of a cell, they tend to be carefully controlled. In this article, we’ll take a look at factors that can affect or control enzyme …
