HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY TGFBR3 (RC216595, 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-TGFBR3 (1:500). Positive lysates LY401117 (100 ug) and LC401117 (20 ug) can be purchased separately from OriGene.
