Fig. 5From: Development of a novel, sensitive translational immunoassay to detect plasma glial fibrillary acidic protein (GFAP) after murine traumatic brain injurySpike recovery of the assay is optimal for specimens with high endogenous GFAP concentrations and sub-optimal for specimens with low endogenous GFAP concentrations. a Five plasma samples were spiked with calibrator at 0, 100, 1000, or 10,000 pg/mL. Mean percent recovery is plotted at each spike concentration with points representing individual spiked sample percent recovery and error bars representing ±SD. Point shapes represent individual plasma samples. %recovery = ((measured concentration spiked sample-measured concentration neat sample)/concentration of spike) × 100%.
