SP6 RNA Polymerase

SP6 RNA Polymerase

High Quality & Proven Performance in RNA In Vitro Transcription Reactions

Product Overview:

SP6 RNA Polymerase is a recombinant protein from SP6 bacteriophage produced in E.coli. Highly specific for the SP6 promoter that makes it distinct from those of analogous enzymes. It catalyzes efficiently the synthesis of RNA from double-stranded DNA.
