Common Use | Dextrans are naturally synthesized polysaccharides with good water solubility, low toxicity and varied molecular weights. Dextran-Cy5 conjugates have excitation/emission wavelength at 650 nm/670 nm, successfully used for live cells. Near IR fluorescent dextrans have better tissue penetration capability and less affected by auto fluorescence arised from biological tissues. These near IR dye labeled dextrans therefore, are good for in-vivo fluorescent imaging applications. These functional dextrans were purified by size chromatography to remove non-conjugated molecules and ensure adequate applications both in-vitro and in-vivo. |
