Concentrations of type XIV collagen determined by quantitative LC-MS/MS analysis with stable isotope-labeled peptides.

*1: Average retention time; Average retention time of triplicate samples (#1: Retention time of one sample, #2: Average retention time of duplicate samples.-: All samples were below detection limit.). *2: Average Conc.; Average intra-assay concentration (n = 3) (#1: Concentration of one sample, #2: Average concentration of duplicate samples, N.D.: Not detected because concentrations of all triplicate samples were not detected, and the concentration was calculated as 0.0.). *3: CV of intra-assay; Coefficient of variation of intra-assay reproducibility (n = 3) (N.C.: Not calculated because concentrations of all tripricate samples were not detected.) *4: Value including interferences *5: Value including detected samples and non-detected samples *6: Average conc.; Average concentration from 2 transitions (614/711and 614/826) for peptide 1 and 3 transitions (708/624, 708/763, 708/877) for peptide 2. *7: Difference of peptide 1; Difference (%) = (Conc. of 614/711-Conc. of 614/826)×100 /Conc. of 614/711, (N.C.: Not calculated because concentration of 614/711 was 0.) #1: Value of 1 sample because other duplicate samples were not detected. #2: Average of duplicate samples because another sample was not detected.
