expression vector
shuttle vector
Restriction digests analyzed on agarose gels give the following sizes (kb): BamHI--5.2; PvuII/HindIII--4.8, 0.3; BglII/EcoRI--3.6, 1.5; AccI/HindIII--3.6, 0.54, 0.44, 0.27; AccI--3.6, 0.96, 0.27; HindIII--5.0; PstI--4.1, 0.9.
Shuttle vector conferring selective advantage to mammalian cell lines grown in the presence of methotrexate. Permits selection in dhfr- cell lines.
Inserts cloned into the PvuII site next to the SV40 late promoter, may be expressed in mammalian cells.
This vector also contains a copy of the mouse dyhydrofolate reductase (dhfr) gene under control of the SV40 early promoter. Dhfr confers methotrexate resistance in Chinese Hamster ovary cells (CHO) which lack dihydrofolate reductase.
This vector does not contain the Large T antigen from SV40.
