Figure 1. Tandem Denaturing Affinity Purification (TDAP) of SUMO targets.

Figure 1

(A) Schematics of TDAP. See the main text for details of the method. (B) Spot assay of the indicated strains on YES plates, with or without hydroxyurea (HU). (C) BH-SUMO expressed from endogenous locus in strains with (+) or without (−) pAdh-driven BirA expression. SUMO conjugates were sequentially purified on Ni-NTA and streptavidin beads. Input and eluate after a single step (Ni) or tandem (Ni-Strep) purification were analyzed by Western blotting with a SUMO antibody. The asterisk marks the position of free BH-SUMO. Sypro Ruby staining of the input is shown on the left as a loading control.
