Plasmid vectors with multiple cloning sites and cat-reporter gene for promoter cloning and analysis in animal cells.
We have constructed two vectors, pGCAT-A and pGCAT-C, designed to facilitate the construction of recombinant plasmids containing the bacterial gene (cat) coding for chloramphenicol acetyltransferase (CAT) under the control of eukaryotic promoter and/or enhancer elements. The cat gene was inserted downstream from a multiple cloning site (MCS) region with eleven unique restriction sites. The MCS region is in opposite orientation in the two vectors. The CAT activity of control extracts from cells transfected with pGCAT-A or pGCAT-C is very low. Insertion of the viral SV40 early promoter into one of the sites of the MCS region of pGCAT-A or pGCAT-C results in a 30- to 400-fold stimulation of the CAT activity.
