SITS Usage And Synthesis
Description

SITS is an amine-reactive fluorescent probe for studying ion transporter.

Chemical PropertiesLight Yellow Solid
UsesA 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.
UsesFluorescent marker for membranes; inhibits anion permeability of membranes. Also inactivates Na,K-ATPase, by covalent modification of a specific Lys residue.
