Streptavidin-dextran conjugates are soluble dextrans with the streptavidin covalently linked to the polymer. The product is water soluble and has strong binding affinity towards biotin. They are versatile polymers that can be used to increase the valency of biotinylated reagents.

Fina Biosolutions provides Streptavidin-dextrans with dextran backbones of 250 kDa, 500 kDa and 2000kDa. The conjugates are purified by size exclusion chromatography to remove non-conjugated molecules. Custom ratios & configurations and bulk amounts are available. Please inquire.
