Equivalent amounts of cell lysates (10 ug per lane) of wild-type Hela cells (WT, Cat# LC810HELA) and RAD23B-Knockout Hela cells (KO, Cat# LC810196) were separated by SDS-PAGE and immunoblotted with anti-RAD23B monoclonal antibody TA804868. Then the blotted membrane was stripped and reprobed with anti-HSP90AB1 antibody (TA500494) as a loading control (1:500).
