Latrunculin A (LAT-A, NSC 613011)

A cell-permeable marine toxin. Disrupts microfilament-mediated processes. Actin polymerization inhibitor in vitro and in vivo by the formation of a 1:1 complex with monomeric G-actin. Depolymerizes actin filaments (F-actin) and acts as a phagocytosis inhibitor. Anticancer compound. Suppresses hypoxia-induced HIF-1 activation in tumor cells. Inhibits tumor cell invasion.\n\nSolubility:\nDMSO, EtOH\n\nMolecular Weight:\n~421.55\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
