 MS/MS analysis of digested peptide and protein identification. (a) The biomolecule of an m/z 1325.6 was identified as histone H4. DNIQGITKPAIR: abbreviation of the amino‐acid sequence aspartic acid–asparagine–isoleucine–glutamine–glycine–isoleucine–threonine–lysine–proline–alanine–isoleucine–arginine. y4, y5, y8, y10, y11 represent each fragment ion, which includes the C‐terminal domain. b5, b6, b7 represent each fragment ion, which includes the N‐terminal domain. (b) The biomolecule with an m/z 976.4 was identified as actin. AGFAGDDAPR: abbreviation for the amino‐acid sequence alanine–glycine–phenylalanine–alanine–glycine–aspartic acid–aspartic acid–alanine–proline–arginine. y2, y3, y4, y7, y8 refer to each fragment ion, which includes the C‐terminal domain.
