  1. Emboldened amino acid indicates stable isotope labeled residue with either Lys -[13C6] [15N2] or Arg -[13C6] [15N4]. Cys residues are carbamidomethylated.
  2. The LOD was determined using a non-parametric method with eight LC-MS analyses without added analyte ((http://clinchem.aaccjnls.org/content/50/4/732).
  3. The LOQ was generated from the LOD (“Algorithms, Routines and S Functions for Robust Statistics” (CRC Press, Boca Raton, Florida, USA, 1993)).
