Dextran, Cy5 labeled

Similar products: Dextran, SF650 labeled, Alexa Fluor 647 Dextran

Description:

Cy5 labeled dextrans (Dextran Cy5) are one of Nanocs premier fluorescent dextrans that emit near infrared light around 670 nm. Cy5 dextran conjugates have excitation/emission wavelength at 650 nm/670 nm. 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. Nanocs provides a variety of chemically functionalized and fluorescent dextran products with molecular weight ranged from 3,000 Da to 2,000 KDa. These functional dextrans were purified by size exclusion chromatography to remove non-conjugated dye molecules and ensure adequate applications both in-vitro and in-vivo.

Dextrans are naturally synthesized polysaccharides with good water solubility, low toxicity and varied molecular weights. Dextrans modified with dyes and other biomolecules have been successfully used as long-term tracers for live cells. Nanocs also provides customized dextran products for your special needs.
