Restriction digests of the clone give the following sizes (kb): EcoRI--3.7; HindIII--3.7; BamHI--3.7; SmaI--3.7; PvuI--2.2, 1.5.
Demonstrates expression inducible by dexamethasone.
A mammalian shuttle vector for expression of a sequence cloned into the polylinker site under the control of the MMTV LTR promoter.
Constructed from pBR322 (2066-4286, bla, ori), SV40 (4038/4648, t antigen IVS), SV40 (2461-2704, T antigen polyadenylation site), and MMTV LTR (-360 to +150, glucocorticoid regulatory sequences, cap site).
