Ated for 16 h at 30 , collected by centrifugation, washed in DDW, and frozen in liquid N2. Ubiquitination Web pages Detection Utilizing GG-Modified Peptide Enrichment. Dried peptides (SI Experimental Procedures, Sample Preparation for MS) had been resuspended in immunoaffinity purification (IAP) buffer (50 mM Mops/ NaOH, pH 7.2, 10 mM Na2HPO4, and 50 mM NaCl), and cleared by centrifugation. Supernatants were adjusted to pH 7.0 with NaOH and incubated with immobilized anti -e-GG antibody (Cell Signaling Technologies) at four for 3 h. Beads have been washed with IAP buffer and then having a wash buffer (500 mM NaCl, 3 mM KCl, 10 mM Na2HPO4, two mM KH2PO4, 0.1 octyl glucoside, pH 7.four). GG-modified peptides were eluted with 0.two TFA, desalted on C18 strategies, and eluted in two fractions of 20 and 80 (vol/vol) acetonitrile. Peptides had been analyzed as described in SI Experimental Procedures, MS. For additional experimental procedures, see SI Experimental Procedures. ACKNOWLEDGMENTS. We thank Drs.
