Ruthenium red 是一种 L 型钙电流 (ICa) 阻断剂，是一种聚阳离子染料，广泛用于电子显微镜 (EM) 下细胞、组织和营养细菌的观察。它能与磷脂和脂肪酸反应强烈，并与酸性粘多糖结合。

Ruthenium Red is a polycationic dye widely used for electron microscopy (EM) of cells, tissues and vegetative bacteria. Ruthenium red strongly reacts with phospholipids and fatty acids and binds to acidic mucopolysaccharides. Ruthenium red is a L-type calcium current (ICa) blocker, blocks Ca2+ uptake and release, and voltage-sensitive Ca2+ channels
