Quality control results of the proteins. A The SDS-PAGE electrophoresis diagram. B Verification of the total protein quality, the abscissa represents the number of amino acid residues in the peptide, and the ordinate represents the number of peptides of this length. C Precursor ion tolerance, the abscissa represents the mass deviation, and the ordinate represents the precursor ion density distribution of the corresponding error. D Unique peptides number, slow increase of the curve means more unique peptides. E protein coverage, the abscissa represents the protein coverage interval, and the ordinate represents the number of proteins contained in the interval (F) Protein mass distribution, the abscissa represents the molecular weight of the identified protein, and the ordinate represents the number of the identified protein. A large molecular weight range indicates a wide range of identified proteins
