HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY EIF2B3 (RC223570, Right lane) cDNA for 48 hrs and lysed. Equivalent amounts of cell lysates (5 ug per lane) were separated by SDS-PAGE and immunoblotted with anti-EIF2B3. Positive lysates LY412535 (100 ug) and LC412535 (20 ug) can be purchased separately from OriGene.
