in another host, produces protein
vector useful for cloning PCR products
Restriction digests of the clone give the following sizes (kb): BamHI--5.8; EcoRI--5.8; HindIII--5.8.
The vector contains a 0.7 kb bovine cDNA that can be excised using the 5' and 3' cloning sites and be replaced by a gene of interest. The bovine insert may be used as a positive control for expression.
One of 12 expression vectors (ATCC 86990-87001) designed to maximize expression from the lambda PL promoter and support cloning of PCR products. The vectors differ in cloning sites and in translational enhancer and initiation sequences.
The bovine insert sequence and ClaI cloning site are out of frame with the lambda cII N-terminal coding sequence, resulting in production of unfused protein from the lambda PL promoter.
