Detailní popis

Thermo Scientific Bacteriophage T3 RNA polymerase is DNA-dependent RNA polymerase with strict specificity for their respective double-stranded promoters. It catalyzes the 5'→3' synthesis of RNA on either single-stranded DNA or double-stranded DNA downstream from it promoter and is able to incorporate modified nucleotide.

Highlights

  • Incorporates modified nucleotides (e.g., aminoallyl-, biotin-, fluorescein-, digoxigenin-labeled nucleotides)

Applications

  • Synthesis of unlabeled and labeled RNA that can be used:
    • For hybridization (see Reference 1), in vitro RNA translation (see​ Reference 2)
    • As aRNA (see​ Reference 3), siRNA (see​ Reference 4), substrate in RNase protection assays (see​ Reference 5), template for genomic DNA sequencing (see​ Reference 6)
    • In studies of RNA secondary structure and RNA-protein interactions (see​ Reference 7), RNA splicing (see​ Reference 8)
     

Note

Consensus promoter sequences:

T3 AATTAACCCTCACTAAAGGGAGA
T7 TAATACGACTCACTATAGGGAGA
SP6 ATTTAGGTGACACTATAGAAGNG

The position in bold (+1) indicates the first nucleotide incorporated into RNA during transcription. Only bases at this position through +3  are critical for transcription, and they must be a G and a purine base, respectively (see​ Reference 9).

5X Transcription Buffer 200 mM Tris-HCl (pH 7.9 at 25°C), 30 mM MgCl2, 50 mM DTT, 50 mM NaCl, 10 mM spermidine.
CategoryName
Definition of Activity Unit
