质粒介绍

       pET-20b质粒是一个大肠杆菌蛋白表达载体，T7启动子驱动目的基因和6×HIS标签融合表达，并在pelB信号肽的作用下分泌至细胞周质。The pET-20b vector carries an N-terminal pelB signal sequence for potential periplasmic localization, plus optional C-terminal His?Tag® sequence. 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. The f1 origin is oriented so that infection with helper phage will produce virions containing single-stranded DNA that corresponds to the coding strand. Therefore, single-stranded sequencing should be performed using the T7 terminator primer.
