T3 RNA Polymerase

T3 RNA Polymerase is a DNA-dependent RNA polymerase that synthesizes RNA using only T3 DNA or DNA templates cloned downstream from a T3 promoter. The polymerase can incorporate ³²P, ³³P, ³H and ³⁵S nucleoside triphosphates during transcription. T3 RNA Polymerase is provided with 100mM DTT and Transcription Optimized 5X Buffer: 200mM Tris-HCl (pH 7.9 at 25°C), 30mM MgCl₂, 10mM spermidine, 50mM NaCl.
