    摘要： A method for the recovery of nucleic acids from a reaction mixture, such as nuclease protection assays, comprising the use of one reagent containing a) nuclease for digesting single-stranded RNA and b) a nucleic acid precipitating carrier agent, (sheared DNA or linear acrylamide). A second reagent contains a chaotropic agent (a guanidinium salt) for inactivating said nucleases and an alcohol (ethanol or isopropanol) for the simultaneous inactivation of the nucleases and the precipitation of the nucleic acids without the need for protease digestion or organic extraction.

    摘要： The present invention relates to compositions and methods for increasing the yields of polynucleotide synthetic reactions. In particular, it relates to an improved reaction mixture for use in in vitro RNA transcription and in various other enzymatic reactions in which a polynucleotide is synthesized. The reaction mixture uses high concentrations of total nucleotides, in the order of 12 mM to 40 mM, i.e. levels that were previously thought to be inhibitory. Other useful modifications are also disclosed.
