活力：20u/ul
活力定义：One unit of enzyme incorporates 1 nanomole of AMP into a polynucleotide fraction(adsorbed on DE-81) in 60 minutes at 37℃
质量控制：Tested for the absence of endo-,exodeoxyribonucleases,ribonucleases and for synthesis of strand-specific RNA
产品描述：Purified from E.coli strains carrying the plasmids encoding the respective RNA polymerases.All those viral RNA polymerases have a stringent specificity for their own promoters and catalyze the synthesis of RNA from ribonucleoside triphosphates in the presence of a DNA template
