Useful:

• Canonical SMILES: CC(=O)NC1=CC(=C(C=C1)C=CC2=C(C=C(C=C2)N=C=S)S(=O)(=O)[O-])S(=O)(=O)[O-].[Na+].[Na+]
• Isomeric SMILES: CC(=O)NC1=CC(=C(C=C1)/C=C/C2=C(C=C(C=C2)N=C=S)S(=O)(=O)[O-])S(=O)(=O)[O-].[Na+].[Na+]
• Uses: A fluorescent label for the specific and reversible labelling of the outer components of the plasma membrane. The reagent reacts with a fixed number of sites on the surface of cells concerned with anion permeation; does not pass through the osmotic barrier of the membrane; reacts under physiological conditions of temperature, pH and tonicity; and is detectable in small amounts. SEE ALSO NOTES FOR DIDS (CAT#D460600). Fluorescence: max. Abs. l = 336nm, max. Em. l = 436 nm. Fluorescent marker for membranes; inhibits anion permeability of membranes. Also inactivates Na,K-ATPase, by covalent modification of a specific Lys residue.
