Fluorescent Dextrans

Fluorescent dextrans have a wide variety of applications. The high water solubility, biocompatibility and range of functionalities make fluorescent dextrans ideal for many applications. They come in an array of molecular weights, fluorescent dyes, dye ratios and additional functional groups. Fluorescent dextrans from Fina Biosolutions use our well-characterized amino dextrans as their base. Our proprietary end-labeling chemistry allows us to synthesize unique multi-functionalized fluorescent dextrans.

We currently stock only a limited number of fluorescent dextrans but many more are in the pipeline. Please contact us for custom dextran reagents.

We provide our fluorescent dextrans as a lyophilized powder.
