Ambion® Yeast tRNA purified from brewer's yeast. When used at a final concentration of 10–20 µg/mL, yeast tRNA is an effective coprecipitant to aid in recovery of small amounts of nucleic acids. It is supplied in one tube containing 0.5 mL at a concentration of 10 mg/mL.
What is a Coprecipitant? Coprecipitants are inert substances used to aid recovery of nucleic acids during alcohol precipitations. While they can be used for precipitating large amounts of nucleic acids, they are essential for quantitative recovery of small amounts of nucleic acids in dilute solutions. Often, the use of such molecules is desirable for no other reason but visualization of the pelleted precipitate after centrifugation.
