The DX1 antibody reacts with dextran, a natural polysaccharide consisting of linear chains of alpha-1,6-linked D-glucopyranose residues with short side chains (mostly 1 - 2 glucose units) 1,3- or 1,4-linked to the backbone of the biopolymer. Dextran has several uses as an additive in food, in lacquers, as a plasma volume expander, and as a coating for particles used in bioimaging or cell separation applications. The DX1 antibody was raised against isomaltotetraose (four sugar units in length) but binds better to longer polymer chains. It is also known to bind to amino-dextran, though with lower affinity. This antibody can be used to detect cells labelled with dextran-coated nanoparticles during StemSep™ and EasySep™ cell separation procedures or for other applications that require the detection of dextran.

This antibody clone has been verified for purity assessments of cells isolated with EasySep™ kits, including EasySep™ Human T Cell Enrichment Kit (Catalog #19051) and EasySep™ Human CD4+ T Cell Enrichment Kit (Catalog #19052).
