Latrunculin A (Invitrogen™)
Latrunculin A disrupts microfilament organization in cultured cells by binding to monomeric G-actin in a 1:1 complex at submicromolar concentrations. Its physiological effects include inhibition of fertilization, early embryological development and phagocytic internalization of immune complexes.
Lissamine™ Rhodamine B 1,2-Dihexadecanoyl-sn-Glycero-3-Phosphoethanolamine, Triethylammonium Salt (rhodamine DHPE) (Invitrogen™)
The phospholipid, rhodamine DHPE is labeled on the head group with the red-fluorescent rhodamine B fluorophore with excitation/emission maxima ~560/580 nm.
Jasplakinolide is a macrocyclic peptide isolated from the marine sponge Jaspis johnstoni and is a potent inducer of actin polymerization in vitro by stimulating actin filament nucleation. Jasplakinolide competes with phalloidin for actin binding (Kd = 15 nM).
