“…20 The protein levels of neutrophil marker (myeloperoxidase [MPO]), T helper (T H ) 1 cell chemokine (CXCL10), and T H 2 cell chemokine (CCL17) in tissue homogenates were measured by commercial enzyme-linked immunosorbent assay (ELISA) kits (Boster Biotechnology, Wuhan, China) according to the manufacturer's instructions. 21 Protein expression data were analyzed and out-of-range values less than the lower limit of detection were assigned 1/10 of the lower limit of detection for the assay as described. 24 The lower detection limits for IFN-γ , IL-12, IL-4, IL-5, IL-13, IL-17A, IL-6, IL-8, eotaxin-1, RANTES, GM-CSF, and G-CSF were 0.74 pg/mL, 0.46 pg/mL, 0.38 pg/mL, 0.56 pg/mL, 0.33 pg/mL, 0.5 pg/mL, 0.36 pg/mL, 0.41 pg/mL, 1.93 pg/mL, 1.1 pg/mL, 0.97 pg/mL, and 0.46 pg/mL, respectively.…”
