HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY IDO2 (RC223337, 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-IDO2. Positive lysates LY403659 (100ug) and LC403659 (20ug) can be purchased separately from OriGene.
