pEF1/myc-His A, B, and C are 6.2 kb vectors derived from pcDNA 3.1/myc-His and designed for overproduction of recombinant proteins in mammalian cell lines. Features of the vectors allow purification and detection of expressed proteins. High-level stable and transient expression can be carried out in most mammalian cells. The vectors contain the following elements:The control plasmid, pEF1/myc-His/lacZ, is included for use as a positive control for transfection, expression, and detection in the cell line of choice.
