  • Patent number: 9528125
    Abstract: The present invention relates to the construction and utilization of a new mammalian expression vector that contains a unique multiple cloning site (MCS), designated pUHAB. The pUHAB vector comprises a high copy replication origin (ColE1), a drug resistance gene (TK-Hygromycin), and a human cytomegalovirus promoter operably associated with a unique intron (hCMV/intron). Further, pUHAB comprises a selectable marker conferring resistance to kanamycin in bacterial cells, and a phage f1(+) region. pUHAB can be used to transiently or stably express cloned genes when transfected into mammalian cells. The invention also encompasses kits and host cells and cell lines comprising pUHAB, and methods of producing a recombinant protein using pUHAB.
