HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY NUB1 (RC208098, 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-NUB1. Positive lysates LY414176 (100 ug) and LC414176 (20 ug) can be purchased separately from OriGene.
