Method Of Extracting A Fraction From A Biological Sample
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.
1 . A method for facilitating extraction of a fraction from a biological sample, the biological sample including non-desired material and a fraction-bound solid phase substrate, the method comprising the steps of:
sequentially drawing an isolation buffer and the biological sample into a barrel of a syringe;
capturing the fraction-bound solid phase substrate; and
bringing the isolation buffer and the fraction-bound solid phase substrate into contact to purify the captured fraction-bound solid phase substrate.
