Dextran, Rhodamine B Labeled


Dextrans are naturally synthesized polysaccharides with good water solubility, low toxicity and varied molecular weights. Rhodamine B labeled Dextran, also called TRITC or RB dextran, is a pink colored dextran conjugate that emits red  fluorescent light upon excited by light at 540-550 nm. Rhodamine B Dextran conjugates from Nanocs have high fluorescent intensity, essentially free of non-conjugated dyes. These products have been successfully used for imaging lymph nodes, neurons, blood vessels and many biological processes. They are also used for long-term tracers for live cells.

Nanocs provides a variety of chemically functionalized and bioconjugated dextran products with molecular weight ranged from 3,000 Da to 2,000 kDa. These functional dextrans were purified by size chromatography to remove non-conjugated molecules and ensure adequate applications both in-vitro and in-vivo. Nanocs also provides customized dextran products for your special needs.


  • 1~50 Rhodamine dyes on each dextran molecule depends on molecular weight of dextran.
