Compositions and methods for increasing the yields of in vitro RNA transcription and other polynucleotide synthetic reactions

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 trancription and in various other enzymatic reactions in which a polynucleotide is synthesised. 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.
