Table 3 Comparison of iTRAQ ratio versus ELISA ratio for sAxl in pooled CSF samples

From: Identification of the soluble form of tyrosine kinase receptor Axl as a potential biomarker for intracranial aneurysm rupture

Group iTRAQ ratio (mean ± SD) ELISA ratio a (mean ± SD) ELISA concentration (nM) (mean ± SD)
RIA 1.68 ± 0.07 2.35 ± 0.24*, #, $ 0.204 ± 0.017 *, #, $
UIA 0.87 ± 0.16 0.98 ± 0.47 0.082 ± 0.030
DC 1.12 ± 0.11 1.52 ± 0.48 0.128 ± 0.022
HC - - 0.088 ± 0.017
  1. aELISA ratio obtained from 3 independent measurements of sAxl concentration in the RIA, UIA, and DC groups divided by the HC group. The differences between groups were analyzed by one –way ANOVA followed by the Newman-Keuls multiple comparison test. *p <0.01 for RIA vs UIA; #p <0.01 for RIA vs HC; $p <0.05 for RIA vs DC.
