简单介绍

pET-51b大肠pET系列表达质粒是一个大��杆菌宠物系列表达质粒,pET-51b(+)向量携带氨基端咽喉炎•**标签编码序列(1)其次是肠激酶rec-ognition网站,和一个可选的c端•标签编码序列。在n端和c端两种“温和洗脱”标记的存在，对于分离全长度融合蛋白(2)的双重净化层是理想的，在圆形图上显示了独特的限制位点。pET-51b大肠pET系列表达质粒注意，序列是由pBR322约定编号的，所以T7表达式区域在圆形映射上是反向的。T7 RNA聚合酶转录的编码链的克隆/表达区域如下图所示。

质粒简介

pET-51b是一个大肠杆菌pET系列表达质粒。The pET-51b(+) vector carries an N-terminal Strep•Tag II coding sequence (1) followed by a rec-ognition site for enterokinase, and an optional C-terminal His•Tag coding sequence. The presence of two "gentle elution" tags at both the N-terminus and C-terminus is ideal for dual puriﬁcation strate-gies designed to isolate full-length fusion proteins (2). Unique restriction 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 circle map. The cloning/expression region of the coding strand transcribed by T7 RNA polymerase is shown below the circle map. The f1 origin is oriented so that infection with the helper phage will produce virions containing single-stranded DNA that corresponds to the coding strand.
