  • SP6 RNA Polymerase is a DNA-dependent RNA polymerase used for in vitro transcription. Only SP6 DNA or DNA cloned downstream from an SP6 promoter can be used as a template for SP6 RNA Polymerase-directed RNA synthesis. The polymerase can incorporate 32P, 33P, 3H and 35S nucleoside triphosphates. SP6 RNA Polymerase is provided with 5X Reaction Buffer: Provided with 100mM DTT and Transcription Optimized 5X Buffer: 200mM Tris-HCl (pH 7.9 at 25°C), 30mM MgCl2, 10mM spermidine, 50mM NaCl. The polymerase is offered as a high-concentration enzyme at 80u/µl (Cat.# P4084).
