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.
