2：葡聚糖分子量：2000/5000/10000/20000/40000/70000/100000 Da

3：葡聚糖改性基团：活化脂NHS/氨基NH2/生物素Biotin/叠氮N3/醛基CHO/巯基SH/马来酰亚胺MAL/炔烃Alkyne/DBCO/Vinyl sulfone

Dextran is a polysaccharides widely used indrug formulations, diagnositic reagent development and in-vivo and in-vitroimaging applications. Ruixibio is a world leader in developing various dextranconjugates with different functionalities and tailored properties. Ourfluorescently labeled dextrans cover a wide range of spectrum from UV region tonear IR area. These fluorescent dextrans include dextrans labeledwith courmarins, fluoresceins (FITC, FAM, etc.), rhodamines (Rhodamine B,Rhodamine 6G, Rhodamine 101, etc.), Cyanine dyes (Cy3, Cy3.5, Cy5, Cy5.5, Cy7,Cy7.5), BODIPY dyes, alexa fluor dyes and many other fluorophores suchas Sun Fluor dyes. We also provide chemically activated dextranconjugates modified by amines, maleimides, NHS, vinylsulfone, azides,DBCO, alkynes and many others.

产品介绍：

Amine functionalized dextrans are one ofNanocs premier reactive dextran conjugates that can be used to react with otherchemical groups. Nanocs provides a variety of chemically functionalized andbioconjugated dextran products with molecular weight ranged from 3,000 Da to2,000 KDa. These functional dextrans were purified by size chromatography toremove non-conjugated molecules and ensure adequate applications both in-vitroand in-vivo.

Dextrans are naturally synthesizedpolysaccharides with good water solubility, low toxicity and varied molecularweights. Dextrans modified with dyes and other biomolecules have beensuccessfully used as long-term tracers for live cells. Nanocs also providescustomerized dextran products for your special needs.
