Amino Dextrans

Amino-Dextran (AmDex, AECM-dextran) consists of dextran functionalized with primary amines (see structural images). Our AmDex is prepared from dextran using a protocol yielding a stable, amino-functionalized dextran that is superior to the more commonly used reductive amination methods. The molecular weight profile of AmDex is essentially unchanged from the starting dextran, as determined by analytical size exclusion chromatography. The product is desalted and lyophilized. We do extensive processing and testing to ensure that free amino reagent is removed, resulting in a consistent product with minimal lot-to-lot variation. We have found that many commercial lots of amino-dextran contain variable amounts of dextran and that the amine content is often incorrect.
