pEF6/V5-His A, B, & C Mammalian Expression Vectors All pEF or pUB vectors contain a strong promoter for high-level expression
in mammalian cells, a choice of selection marker for generating stable
cell lines, and an epitope tag for easy detection with a monoclonal antibody
and rapid purification on nickel-chelating resin. Each vector is available
in three reading frames to simplify cloning in-frame with the fusion tag.
