pWHERE

pWHERE plasmid was designed for studies of temporal expression and tissue distribution of your promoter of interest, cloned within an insulated LacZ cassette, in transgenic mice and rats. A multiple cloning site (MCS) has been added upstream of the LacZ gene for convenient cloning of your promoter of interest.

pWHERE can be purchased alone or as part of a kit containing the pWHERE control plasmid with the rat EF-1α promoter.
