Fig. 1: Lymphatic fluid contains several tryptophan metabolites.
From: 3-hydroxy-L-kynurenamine is an immunomodulatory biogenic amine
a Bar graphs reporting the MS1 area of tryptophan metabolites detected in the human lymph. Bar graphs represent MS1 average readings ± SD of n = 3 biological replicates. Source data are provided as a Source data file. b Standards used for identification/quantification of 3-hydroxykynurenamine (3-HKA) vs 5-hydroxy-l-kynurenamine by mass spectrometry. c 3-HKA was reacted with dansylchloride producing the di-dansylated 3-hydroxykynurenamine derivative (Supplementary Figs. 1 and 2). The stable derivatization product was quantitatively analyzed by HPLC-DAD.
