MilliporeSigma™ pET-23a(+) DNA Vector

Description

The pET-23a-d(+) vectors carry an N-terminal T7·Tag™ sequence plus an optional C-terminal His·Tag™ sequence. The sequence is numbered by the pBR322 convention, so the T7 expression region is reversed on the vector map. The f1 origin is oriented so that infection with helper phage will produce virions containing single-stranded DNA that corresponds to the coding strand.
