Nitrite as Direct S-Nitrosylating Agent of Kir2.1 Channels
Figure 3
(a) Western blot of S-nitrosylated proteins in membrane fraction of ventricle homogenates of control, nitrite, GSNO, PTIO, PTIO + nitrite, and NONOATE treated heart. Blot is representative of 3 independent experiments. (b) Densitometric analysis of the protein band corresponding to 50 kDa. Data are means ± SE of 5 determinations for each animal (). Statistical differences were evaluated by Student’s -test; .
