Invitrogen Molecular biology grade, 0.5 M EDTA, pH 8.0 solution is supplied in one bottle. The solution is certified RNase-free, economical, and ready-to-use.
Invitrogen Yeast tRNA purified from brewer's yeast. When used at a final concentration of 10 to 20 μg/mL, yeast tRNA is an effective coprecipitant to aid in recovery of small amounts of nucleic acids.
Purified Torulla Invitrogen 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.
Purified Saccharomyces cerevisiae yeast RNA is is a very effective blocking agent when used in Northern prehybridization and hybridization buffers, as well as being suitable as a coprecipitant in nucleic acid precipitations.
