Figure 2

Representative chromatogram for [Pyr1]apelin-13 and its internal standard in volunteer samples. (A,B) chromatograms for samples obtained at t = 0 minutes; (C,D) chromatograms for samples obtained at t = 120 minutes. (A) no [Pyr1]apelin-13 was detected; (B) [Pyr1]apelin-13 internal standard chromatogram showing 3.67 minutes retention time; (C) [Pyr1]apelin-13 chromatogram showing 3.68 minutes retention time; (D) [Pyr1]apelin-13 internal standard. MRM = multiple reaction monitoring.
