Noninvasive Analysis Using Data-Independent Acquisition Mass Spectrometry: New Epidermal Proteins That Reveal Sex Differences in the Aging Process

Figure 1

(a) Identification of DDA profiles for subsequent DIA quantification: unique peptide distribution with the horizontal axis being the only matching peptide number per protein and the vertical axis being the number of proteins; (b) protein mass distribution with the horizontal axis being the protein mass interval (Kilodalton) and the vertical axis being the corresponding protein number; (c) protein coverage distribution with the horizontal axis being the percentage protein coverage interval and the vertical axis being the number of proteins. (d, e) Unique proteins and peptides were counted in each sample collected by Q Exactive HF in the DIA mode.
