ADMA lowering in plasma by PA-DDAH-beads. (a) Different amounts of PA-DDAH-beads were incubated with pig plasma containing 2 μM ADMA for 30 min at room temperature. The mixture was then lightly centrifuged to separate beads from the plasma. ADMA in the plasma was determined using HPLC method (n=3). (b) 10 μL of PA-DDAH-beads were incubated with pig plasma for various times at room temperature and ADMA was determined using HPLC method (n=3). All data are given as mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001.
