pGilda酵母双杂交质粒

原核抗性： 氨苄青霉素Amp 筛选标记： HIS3 克隆菌株： 大肠杆菌DH5α 培养条件： 37℃

pGilda is a cloning vector used to generate fusions of a bait protein with the 202-residue LexA protein, which acts as a DNA-binding domain in the MATCHMAKER LexA Two-Hybrid System . The hybrid protein is expressed in yeast cells from the tightly regulated GAL1 promoter (PGAL1); transcription is repressed in the presence of glucose and induced in the the absence of glucose and presence of galactose . pGilda carries the HIS3 gene for selection in His– auxotrophic yeast strains and is compatible with MATCHMAKER LexA Libraries. This vector replicates autonomously in both E. coli (using the Col E1 ori) and in S. cerevisiae (using the CEN/ARS ori). Ampr is used for selection in E. coli.
