T7 promoter sequencing primer, 20-mer

This primer anneals to the T7 Promoter region of any vector containing the T7 Promoter.

Contribution: New documentation from Evry_Paris-Saclay 2020

This part is the strong promoter from T7 bacteriophage (taatacgactcactata) with GGG at 3' end.

The T7 RNA polymerase initiates the transcription at the first guanidine of this stretch of three G and it was shown that +1 GGG is one of the best +1, +2 and +3 base combinations at the transcription initiation for enhanced promoter strength [1].
