Fig 1: Box plots illustrate the ELISA validation results of four candidate CAL biomarker proteins. Following iTRAQ assay, four candidate serum proteins were validated with ELISA on all serum samples. With statistical significance, CAT and S100A4 kept higher levels in CAL-KD and CAL+KD samples, respectively. CAT—catalase; CLC—galectin 10; FOLR3—Folate receptor gamma; S100A4—S100 calcium-binding protein A4; CAL—coronary artery lesion; KD—Kawasaki disease.
