Original recordings showing the effects of 0.3‐3 μM R‐L3, 10 μM chromanol 293B, 10 μM HMR1556, 0.5 mM 4 aminopyridine (4‐AP) and 10–30 μM XE991 on arterial tone of isolated mesenteric artery rings without PVAT (−) fat. Mesenteric arteries were either precontracted with 1 μM phenylephrine (PE) (A,B,C) or with 60 mM KCl (D). Effects of chromanol 293B (A) and HMR1556 (B) on arterial tone induced by PE. All vessels were from wild‐type (Kcnq1
+/+) mice.
