Latrunculin A (LAT-A, NSC 613011)
100ug
Biochemicals Storage: 4C/-20CShipping: Blue Ice
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.

Solubility:
DMSO, EtOH

Molecular Weight:
~421.55

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. 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.
