Antonia Red™ is a red-shifted dye with an absorbance maximum at 583 and an emission wavelength of 602 nm. All batches are carefully controlled for molecular weight, appearance, solubility, degree of substitution, fluorescence and free dye. Aladdin produce Antonia Red-dextran from 4 kDa to 150 kDa. Antonia Red-dextrans are supplied as a purple powder.

Structure

Antonia Red™- dextran are synthesised from well-characterised dextran fractions derived from Leuconostoc mesenteroides. The dextran fractions are then labelled with Antonia Red. The degree of substitution lies between 0.001-0.01.

Spectral data

Antonia Red™-dextran has an absorbance maximum at 583 nm and an emission wavelength of 602 nm in borate buffer at pH 9.0.

Application

Antonia Red™-dextran is mainly used for studying permeability and microcirculation. It can also be used as a molecular size marker, for studies of drug delivery and more. Antonia Red shows bright fluorescence, has good photo- and chemical stability and is non-pH dependent.Antonia Red dextrans 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 dextrans is brightly fluorescent using the red (Texas Red) filter in fluorescence microscopy.
