HEK293T cells were transfected with the pCMV6-ENTRY control (Cat# PS100001, Left lane) or pCMV6-ENTRY APCS (Cat# RC202802, 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-APCS (Cat# TA505248). Positive lysates [LY400617] (100 ug) and [LC400617] (20 ug) can be purchased separately from OriGene.
