HEK293T cells were transfected with the pCMV6-ENTRY control (Cat# PS100001, Left lane) or pCMV6-ENTRY TGFBI (Cat# RC200411, 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-TGFBI (Cat# TA805390)(1:500). Positive lysates [LY424775] (100 ug) and [LC424775] (20 ug) can be purchased separately from OriGene.
