Latrunculin B (76343-94-7) inhibits actin polymerization and disrupts microfilament organization.1 Significantly more potent than cytochalasins in the disruption of microfilament mediated processes2, causes shortening and thickening of stress fibers. Active in cell culture.3,4 Effective doses for latrunculin B vary depending upon cell type but are frequently in the low micromolar range. Note: Latrunculin B is slowly inactivated by fetal bovine serum.
