Method Of Extracting A Fraction From A Biological Sample

Abstract

A method is provided for facilitating extraction of a fraction from a biological sample. The biological sample includes non-desired material and a fraction-bound solid phase substrate. The method includes the steps of capturing the fraction-bound solid phase substrate and bringing an isolation buffer and the fraction-bound solid phase substrate into contact to purify the captured fraction-bound solid phase substrate.
