  1. aThe concentration of biothiols in human serum is determined by using the standard addition method (Fig. 5b). The concentration of Cys in human serum is measured to be 140.79 ± 9.42 µM using Cysteine Assay Kit (Fluorometric) (Abcam, United Kingdom), and the mean and standard deviation are estimated from triplicate measurements.
  2. bMean of three measurements.
  3. cStandard deviation of three measurements.
  4. dCoefficient of variation = SD/mean × 100.
  5. eMeasured value/added value × 100.
