CD207, also known as langerin, is a 40 kD single-pass type II transmembrane protein, member of the C-type lectin family. CD207 is expressed on the cell surface and Birbeck granules (BGs) of Langerhans cells, and subsets of thymic and splenic dendritic cells. Its ligands are mannose, n-acetylglucosamine, fucose, and sulfated glycans. Langerin is involved in the antigen processing pathway through capture and internalization of its ligands.

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 microg per million cells in 100 microL volume. It is recommended that the reagent be titrated for optimal performance for each application.
