Description
pTK-Hyg is a selection vector that confers hygromycin resistance in mammalian cells for the
selection of stably transformed cells. pTK-Hyg is especially useful for selection of double-stable
cell lines using the Tet-On® or Tet-Off® Gene Expression Systems because the absence of an
enhancer element on pTK-Hyg prevents the unwanted activation of pTRE- and pBI-derived
plasmids upon cointegration into the host cell's genome.
Use
pTK-Hyg can be cotransfected into the host cell line with an expression plasmid that contains
a gene of interest using any standard transfection technique. Most mammalian cell lines
require 200 µg/ml of Hygromycin to select for stably transformed cells.
