75Se labeling. The left lane shows cells transfected with a GFP–SelJ construct, and the right lane shows cells transfected with a control vector. Migration of endogenous selenoproteins TR1 and GPx1 is indicated by arrows on the right. Migration of the 45-kDa GFP–SelJ fusion selenoprotein is shown by an arrow on the left.
