pACYC184质粒是一种原核表达载体,含有p15A复制起点的大肠杆菌质??寺≡靥?。这允许pACYC184在与ColE1相容性组的质粒(例如pBR322,pUC19)的细胞共存。它是一个低拷贝数载体,每个细胞约15个拷贝,但可以用壮观霉素放大。由于cat基因的存在,氯霉素不能用于扩增。
pACYC184 is an E. coli plasmid cloning vector containing the p15A origin of replication (1-4). This allows pACYC184 to coexist in cells with plasmids of the ColE1 compatibility group (e.g., pBR322, pUC19). It is a low copy number vector, at about 15 copies per cell (5), but can be amplifed with spectinomycin. Chloramphenicol cannot be used for amplifcation due to the presence of the cat gene.
