T7 RNA Polymerase Kit
Efficient transcription of mRNA of different lengths
Fig. 1 Three plasmids (lane 1 with poly A tail, lane 2 and 3 without poly A tail) were used as templates, and the reaction was 2 h at 37 °C in the 20 μl system, and the transcription length was 2000 nt, 4000 nt, and 2000 nt, respectively. The above mRNA was not purified.

Cautions
(1) it is recommended to add DNA template at last to prevent Spermidine in the 5× transcription buffer precipitates the DNA template.
(2) The DNA template is pre cut into flat ends or 5'protruding ends, which is conducive to the effective transcription of specific regions.
(3) In order to avoid the influence of protein and salt ions on the system, it is suggested that the plasmid be purified after linearization and then used as a template for in vitro transcription.
