Beschreibung

Stability Hygroscopic, Temperature Sensitive
Applications 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.
