大肠杆菌的趋化性被一种钙离子通道阻滞剂ω-芋螺毒素所抑制。用Tris-EDTA透化的细胞，纳摩尔水平的ω-芋螺毒素抑制趋化性而不丧失运动性。用ω-芋螺毒素处理的细胞以平滑偏差游动，即，翻滚被抑制。
Escherichia coli chemotaxis was inhibited by omega-conotoxin, a calcium ion channel blocker. With Tris-EDTA-permeabilized cells, nanomolar levels of omega-conotoxin inhibited chemotaxis without loss of motility. Cells treated with omega-conotoxin swam with a smooth bias, i.e., tumbling was inhibited.
