Figure 4From: Expression changes of ionic channels in early phase of cultured rat atrial myocytes induced by rapid pacing Expression of L-type calcium channel α 1 c by immunocytochemistry (200×). (A: Expression of L-type calcium channel α1c before pacing; B: Expression of L-type calcium channel α1c at 3 h after pacing; C: Expression of L-type calcium channel α1c at 12 h after pacing; D: Expression of L-type calcium channel α1c at 24 h after pacing).Back to article page
