| Applications： | Expression vector for creating transgenic mice
Shuttle vector |
| Comments： | Restriction digests of the clone give the following sizes (kb): BamHI--7.0; EcoRI--7.0; XbaI--7.0.
The promoter is followed by a portion of the rabbit beta-globin gene, which provides a splice and a polyadenylation signal and is thought to provide a nuclear export signal.
The BamHI cloning site may be prone to problems with cryptic splice donors leading to truncated transcripts.
Elimination of non-essential plasmid sequence before microinjection of a recombinant vector may increase expression efficiency
in the mouse. After insertion of the target gene, the pBR322 portion of the vector can be digested with one of the following enzymes to provide a linear molecule for microinjection: AatII, BglI, XbaI, NruI or HhaI.
Shuttle expression vector used to target expression of a cloned gene to murine cells which normally display MHC class II molecules.
The order of the major features in the plasmid is: Ea promoter - BamHI - beta-globin sequence/EcoRI - XhoI - pMB1 ori - ampR - XbaI. |
