General description
Antonia Red™ dextrans are purple powders that are readily soluble in water or electrolytesolutions. Antonia Red dextran are insoluble in most organic solvents.
Application
Antonia Red™ dextranes are primarily used for studying permeability and transport in cells and tissues, trace cell lineage and perform vasculature studies. An added benefit is that measurements of the fluorescence provide quantitative data on the permeability of healthy and diseased tissues. Such studies can be performed in real time by intra-vital fluorescence microscopy. The technique offers high sensitivity and concentrations down to 1μg/ml can be detected in tissue fluids. Antonia Red™ dextranes is brightly fluorescent using the red (Texas Red®) filter in fluorescence microscopy.
Other Notes
The dextran used is essentially a linear α-(1-6)-linked glucose chain with a low percentage (2-5%) of α-(1-3) branches distributed along the chain.
