[Increase in the in vitro activity of mollicute transcriptase using substances of an organic nature]

It is established that the use of DNA-dependent RNA-polymerases of mollicutes in the molecular-biological and gene-engineering works aimed to obtain a sufficient amount of the transcription products may promote a 1.5-2-fold increase of the yield by introducing such substances as glycerol, dimethylsulphoxide and spermidine (optimal concentrations: 10-12 vol. % and 12 mM, respectively) into the composition of the reacting mixture.
