Abstract
The invention relates to a process for reducing RNA concentration in a mixture of biological material, comprising the steps of: (a) providing a mixture of biological material having a first concentration of RNA; (b) filtering the mixture through a diatomaceous earth material to produce a filtrate having a second concentration of RNA, wherein the second concentration is less than the first concentration; and (c) collecting the filtrate having a reduced RNA concentration.
