Product Description T7 RNA Polymerase is the key enzyme for in vitro transcription of mRNA. It efficiently incorporates standard or modified nucleoside triphosphates (NTPs) into RNA transcripts. T7 RNA Polymerase initiates transcription at the G* in the classic T7 promoter-taatacgactcactataG*GG. When using GAG cap1-Analog for co-transcription, taatacgactcactataA*GG is recommended.

Note:
Restriction enzymes that produce blunt ends or 5'-overhangs are recommended.
The cofactor Mg2+ is required for the synthesis.
Application In vitro transcription, RNA analysis, Radiolabeled RNA probe preparation, Hybridization, RNase protection assay

Figure 1. Three plasmids (lane 1 with poly A tail, lane 2 and 3 without poly A tail) were used as templates in a 2-hour reaction at 37 °C in a 20 μl system. The transcription length was 2000 nt, 4000 nt, and 2000 nt, respectively. The mRNA was not purified.
Figure 2. Detection of T7 RNA Polymerase by molecular beacon. The detection principle is that when the molecular beacon and transcript specifically bind, the conformation changes and the fluorescence intensity changes. Three batches of T7 RNA Polymerase were detected with a similar slope across all batches, indicating stable activity across batches.
Figure 3. Yield was assessed via nanodrop and Agilent 4150. Purity was assessed by CE. Overall, KACTUS T7 RNA Polymerase showed yield and purity comparable to those of leading competitors.
