CD209 molecule is a transmembrane receptor and is often referred to as DC-SIGN because of its expression on the surface of dendritic cells and macrophages. The encoded protein is involved in the innate immune system and recognizes numerous evolutionarily divergent pathogens ranging from parasites to viruses with a large impact on public health. The protein is organized into three distinct domains: an N-terminal transmembrane domain, a tandem-repeat neck domain and C-type lectin carbohydrate recognition domain. The extracellular region consisting of the C-type lectin and neck domains has a dual function as a pathogen recognition receptor and a cell adhesion receptor by binding carbohydrate ligands on the surface of microbes and endogenous cells. The neck region is important for homo-oligomerization which allows the receptor to bind multivalent ligands with high avidity. Variations in the number of 23 amino acid repeats in the neck domain of this protein are rare but have a significant impact on ligand binding ability.

We provide highly purified Virus-Like Particles (VLPs) products as antigens, produced in a native format, mostly using a mammalian expression system. Custom VLPs synthesis is also offered presented as a cell lysate or a purified antigen for use in vaccine development (including use as an immunogen) and serological based diagnostic assays. We like to be in touch with our customers so please feel free to contact us for a formal quote.
