Fig. 3From: Characterization of the major human STAG3 variants using some proteomics and bioinformatics assaysSTAG3 knockdown in MCF-7 cells using specific si-STAG3. To help identify which band represented STAG3, lysates of MCF-7 cells already transfected with scrambled (control) siRNA, si-STAG3#1, or si-STAG3#2 were run on SDS-PAGE and then Western blotted. The labeled bands represent the putative STAG3 proteinsBack to article page
