KEAP1 mass spectrometry analysis For mass spectrometry analysis, 10 g of recombinant human KEAP1 (#11981-H29B-100, Sino Biologicals, Beijin, PR China) were diluted to 100 l with 20 mM Tris pH 8.0 and diafiltrated by means of a Amicon Ultra-0.5 ml device (Sigma-Aldrich, Milan, Italy) to eliminate GSH, and then treated with 30 mM M DTT and incubated 30 min at room temperature to reduce the disulfide bridges, diafiltrated to remove the excess of DTT and diluted in 20 mM Tris pH 8.0
