产品简介：

    肌动蛋白破坏用于研究体外(例如，迁移、胞吞作用)和体内(例如，肿瘤细胞侵袭)的细胞功能。Latrunculin A是一种具有生物活性的2-噻唑烷酮大环内酯，来源于海绵，可隔离G-肌动蛋白并阻止F-肌动蛋白装配。它以1:1的化学计量结合单体肌动蛋白，可用于在体外(Kd = 0.2微米)和细胞内(0.5微米，30分钟)阻断肌动蛋白聚合。[1]、[2]、[3] Latrunculin A (1-10微米)在十分钟内引起肿瘤细胞细胞骨架的解聚。[4]用latrunculin A (10微米)过夜处理细胞强烈抑制肌动蛋白合成。[5]延长的细胞处理阻断了地塞米松诱导的肌动蛋白细胞骨架的变化，而对细胞活力没有影响。[6]
