Properties
Description
Red dextran is a substance from carefully analyzed dextran fractions combined with red-shifted dye and provided as a water-soluble purple powder. At a pH of 9.0 in borate buffer, it possesses an absorbance peak frequency of 583 nm and an emission wavelength reaching 605 nm. Red dextran is a high-quality product with a molecular weight of 140,000-160,000 and a degree of substitution of 0.001-0.01.
