HEK293T cells were transfected with the pCMV6-ENTRY control (Cat# PS100001, Left lane) or pCMV6-ENTRY SYNPO (Cat# RC228616, 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-SYNPO antibody (Cat# TA890150). Positive lysates [LY426310] (100ug) and [LC426310] (20ug) can be purchased separately from OriGene.
