■ 质粒简介
pET-3a载体是一个大肠杆菌表达载体，T7启动子驱动T7标签和目的基因融合表达。该载体是组成型表达，并且不携带6×HIS标签。The pET-3a-d vectors carry an N-terminal T7•Tag sequence and BamH I cloning site. These vectors are the precursors to many pET family vectors; the pET-23a-d(+) series corresponds to pET-3a-d but incorporates several additional features. Unique sites are shown on the circle map. Note that the sequence is numbered by the pBR322 convention, so the T7 expression region is reversed on the circular map. The cloning/expression region of the coding strand transcribed by T7 RNA polymerase is shown below.
