|Further information:||This plasmid was constructed as follows: 1) a PCR was performed using pCAGGS as template; 2) the PCR fragment was cloned as a SnaBI(Eco105I)/XhoI fragment in the SnaBI/XhoI opened pCAGGS. As a result, the T7 promoter was inserted downstream of the AG promoter.
The AG promoter sequence consists of the chicken β-actin promoter, the first exon and part of the first intron (that seems to have a strong enhancer-like activity) linked to a rabbit β-globin fragment, consisting of a 3' part of the second intron (inclusive a branch point which is required for normal splicing reactions) and a 5' part of the third exon.
When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT726974.1.
