Differences in primary antibody specificity between assays. (A) Pooled urine sample with low concentration of 11-dehydro TXB2 were spiked with an increasing concentration of the indicated thromboxane metabolites and apparent 11-dehydro TXB2 levels determined by polyclonal (left panel) and monoclonal antibody-based ELISA (right panel). (B) Correlation between urine 11-dehydro 2,3-dinor TXB2 and 11-dehydro TXB2 levels determined by performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS).
