Fig. 4From: iTRAQ-based proteomic profiling reveals protein alterations after traumatic brain injury and supports thyroxine as a potential treatmentParallel reaction monitoring outcomes. a Comparison of fold changes of some proteins between iTRAQ and PRM methods. A fold change > 1 indicates upregulation. b Retention time and intensity of two peptides of Ttr fitted from four samples each group (upper). Peak areas of two peptides were displayed as a histogram belowBack to article page
