Recombinant Human DC-SIGN/CD209 Fc Chimera Protein, CF Summary

Additional Information
A New and Improved rh DC-SIGN is Now Available! The new protein has enhanced purity and a HA-tag!
Details of Functionality
Measured by the ability of the immobilized protein to support the adhesion of ICAM-3 expressing CHO Chinese hamster ovary cells. When 5 x 104 cells/well are added to Recombinant Human DC‑SIGN/CD209 Fc Chimera coated plates (5 µg/mL with 100 µL/well), approximately 50-80% of added cells will adhere after 1 hour at room temperature.
Optimal dilutions should be determined by each laboratory for each application.

Human Dendritic Cell-specific ICAM-3 Grabbing Non-integrin (DC-SIGN)/CD209 is a member of the C-type lectin family (1). The canonical DC-SIGN/CD209 isoform is a 46 kDa, 404 amino acid (aa) type II transmembrane protein (2). The extracellular region contains a Ca2+-dependent carbohydrate-binding lectin domain (2). Multiple human DC-SIGN/CD209 splice forms exist, generating both membrane-bound and soluble forms (3). DC-SIGN/CD209 is not well conserved between mouse and human, with the extracellular domain sharing only 63% aa identity. The DC-SIGN/CD209 lectin domain binds mannose oligosaccharides on pathogens including HIV as well as self glycoproteins including ICAMs (2, 4). DC-SIGN/CD209 is expressed on dendritic cells (DC) and inflammatory macrophages and contributes to antigen presentation (5, 6).
