Methylarginine standard curves measured using UHPLC-MS/MS. (A) L-NMMA (purple), ADMA (green) and SDMA (red) elute at different retention times (mins) from the UHPLC column. The standard curves for (B) ADMA, (C) L-NMMA (D) and SDMA are displayed with the goodness of fit, represented by the r² values.
