Representative spectra of media sections spotted with peptide/protein standards mixed with saturated matrix in 50% ACN, 0.1% TFA. (A) OCT media with CHCA; (B) TBS media with CHCA; (C) 5% CMC + 10% gelatin media with CHCA; (D) OCT media with SPA; (E) TBS media with SPA; (F) 5% CMC + 10% gelatin media with SPA. See Supplemental Fig. 2 for spectra representing the remaining five media types that also did not suppress peptide or protein ions.
