Correlation of four protein targets in bead-based and aptamer-based assays. a The relative fluorescence units (RFU) of each of the 4 proteins (IL-1A, IL-1RA, TNFα and IL-6) in 28 plasma samples were derived from the Milliplex, SOMAscan and Discovery assays and tested for correlation (Spearman’s rank correlation coefficient). b The absolute protein concentrations (pg/ml) of each of the 4 proteins (IL-1A, IL-1RA, TNFα and IL-6) in 28 plasma samples were derived from the Milliplex and Discovery assays and tested for correlation (Spearman’s rank correlation coefficient)
