Yeast RNA (10 mg/mL)

Purified Torulla Ambion™ yeast RNA is suitable as a coprecipitant in nucleic acid precipitations.It cannot be used in reactions inhibited by exogenous RNA, and it is the most inexpensive source of a high-quality coprecipitant.This total RNA preparation is supplied in ten 1 mL tubes at a concentration of 10 mg/mL in diethyl pyrocarbonate-treated distilled water.It is typically used at a working concentration of 10–20 µg/mL.

What is a Coprecipitant?
Coprecipitants are inert substances used to aid recovery of nucleic acids during alcohol precipitations.大量の核酸を沈殿させるのにも使用できますが、希薄な溶液中の少量の核酸を定量的に回収するためには必須です。多くの場合、このような分子の使用は他の理由なく望ましいことですが、遠心分離後に沈殿した沈殿物を視覚化することが望ましいことがあります。
