Fig. 5. Immunoprecipitations of lysates from NB4-LR1/hTERT cells with NCL-hTERT or nucleolin antibodies and immunoblotting with both antibodies. Positions of the molecular weight markers are indicated on the left. Positions of the proteins of interest are indicated by arrows. Position of the heavy chain (Ig) of antibodies is shown. IgG, control for nonspecific binding by performing immunoprecipitation reaction using normal mouse or rabbit IgG.
