Targeted liquid chromatography tandem mass spectrometry to quantitate wheat gluten using well-defined reference proteins
Fig 3
Linear Pearson correlations between gluten contents and concentrations of peptides from all wheat gluten protein types.
(A) Peptide P4 from low-molecular-weight glutenin subunits (LMW-GS), (B) P7 from high-molecular-weight glutenin subunits (HMW-GS), (C) P8 from γ-gliadins, (D) P11 from α-gliadins, (E) P14 from ω5-gliadins, (F) P15 from ω1,2-gliadins. The presented peptides showed the highest correlation coefficients within the respective protein type (see Table 3).
