HEK293T cells were transfected with the pCMV6-ENTRY control (Cat# PS100001, Left lane) or pCMV6-ENTRY CGB7 (Cat# RC208311, 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-CGB7 antibody (Cat# TA890044). Positive lysates [LY409707] (100ug) and [LC409707] (20ug) can be purchased separately from OriGene.
