Western blot using Eif3e polyclonal antibody (Cat # PAB10203) shows detection of endogenous Eif3e in whole cell extracts from murine (HC-11 and NIH/3T3), monkey (CV-1 and COS-1), and human (HEK293T) cell lines as well as over-expressed Eif3e (control transfected flag-tagged Eif3e). The identity of the higher and lower molecular weight bands is unknown. The band at ~48 KDa, indicated by the arrowhead, corresponds to flag-tagged Eif3e. Primary antibody was used at 1:1000.

Western Blot (Recombinant protein)
Western blot using Eif3e polyclonal antibody (Cat # PAB10203) shows detection of endogenous Eif3e. Specific staining is not present in lysates containing lentiviral knockdown vectors (shRNA #1 and #2. Control vectors, specifically a scrambled sequence (Ctl NS) and a sequence against an unrelated gene (Ctl #2), were also used. Personal communication, J.Lee, NCI, Bethesda, MD.
