From: Clinical and analytical comparison of six Simoa assays for plasma P-tau isoforms P-tau181, P-tau217, and P-tau231

Parallelism of the six P-tau assays. Serial dilution of four plasma samples (in green, solid lines) and one calibrator (in purple, dashed line) was performed for each of the P-tau assays. Plasma samples with relatively high endogenous P-tau concentrations were selected for the parallelism experiment. For P-tau231 Gothenburg, one sample showed no signals upon dilution for the 8- and 16-fold dilutions. Crosses represent the individual measurements. A linear slope was fitted for each sample and for the calibrator, the equation of which is presented in the figures
