Quality control of protein quantitative in proteomic analysis. A The elution time of corrected peptide (iRT), vertical axis: retention time, horizontal axis: loading order. B FDR distribution map. Cscore: equivalent to protein reliability score, the higher the score, the greater the reliability. Horizontal axis: Cscore value of protein; Vertical axis: the number of proteins under a certain Cscore score. Black dotted line: 1% Q-value (equivalent to 1% FDR) standard line, the higher the Cscore at the standard line, and the higher the reliability. C Box diagram of CV value distribution of QC, the median CV value of QC samples was 8.7%. D Correlation analysis of QC samples. Log values of intensity values were marked on the horizontal axis and vertical axis respectively, and correlation coefficients greater than 0.9 indicating a high correlation
