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.
Applications
- Generation of templates for in vitro translation.
- Generation of probes for nucleic acid hybridizations.
- Generation of RNA processing substrates.
- Generation of antisense RNA.
