pLIVE

The pLIVE® vector (Liver In Vivo Expression) is designed for high level, prolonged expression of transgenes in the mouse liver. This vector utilizes a chimeric promoter composed of the mouse alpha fetoprotein enhancer II and the minimal mouse albumin promoter. Two introns have been engineered into the vector to increase the expression of the delivered transgene. Downstream of the first intron is a multiple cloning site (MCS) with eight unique restriction sites allowing for simple insertion of the gene of interest. Together the chimeric promoter and two introns are capable of promoting high level transgene expression in the liver for extended lengths of time compared to classic promoters such as the CMV immediate early promoter.

In addition to the pLIVE ® Vector, two reporter vectors derived from pLIVE, pLIVE-LacZ (encoding β-galactosidase) and pLIVE-SEAP (encoding Secreted Embryonic Alkaline Phosphatase), were created for use as positive controls. Expression of the LacZ gene from pLIVE-LacZ can be monitored in the liver using either classical X-gal staining of liver sections or quantitative ß-galactosidase assays of liver lysates. Expression of the SEAP gene from pLIVE-SEAP can be easily monitored using a quantitative assay of mouse serum. The high level, long term liver-specific expression of transgenes from the pLIVE ® Expression Vector, as well as the availability of the positive control pLIVE ® -lacZ and pLIVE ® -SEAP Reporter Vectors, make the pLIVE ® Vector series the ideal choice for in vivo liver expression studies in mice.
