Replaces Prod. #: ALX-350-036
Structurally unique marine toxin. Actin filament modulator. 10- to 100-fold more potent than cytochalasins. Whereas cytochalasin D (Prod. No. BML-T109) induces dissolution of F-actin and stress fiber contraction in fibroblasts in culture, latrunculin B causes a shortening and thickening of stress fibers. Effects on N1E-115 cells (mouse neuroblastoma) at concentrations as low as 90nM (NI43T3 cells, 0.9µM). Maximum effects at 2.5µM. Slowly inactivated by fetal bovine serum. Inhibition of cofilin-actin binding (ED50~50µM)
