Figure 1. Comparison of FGF23 assay kit standards.

Figure 1

Intact FGF23 assay kit standards were measured on the C-terminal FGF23 ELISA (1A) and the C-terminal FGF23 kit standards were measured on the Intact FGF23 ELISA (1B). The ratio of intact FGF23/C-terminal FGF23 for both sets of assay standards is plotted according to the concentration of the assay standard (1C). Diamonds indicate intact FGF23 assay kit standards and circles indicate C-terminal FGF23 assay kit standards.
