HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY E2F5 (RC224285, 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-E2F5 (1:2000). Positive lysates LY419631 (100 ug) and LC419631 (20 ug) can be purchased separately from OriGene.
