PeproTech's CHO-derived Recombinant Human ICAM-3 Fc is a glycosylated, disulfide-linked homodimer of 689 amino-acid-residues whose monomer consists of the 456-amino-acid extracellular portion of ICAM-3 fused to the 231-amino-acid length Fc portion of human IgG by two glycine residues. The calculated molecular weight of monomeric CHO cell-derived Recombinant Human ICAM-3 Fc is 75.5 kDa; however, due to glycosylation, it migrates at an apparent molecular weight of approximately 130-140 kDa by SDS-PAGE analysis under reducing conditions.

CD50 (intracellular adhesion molecule 3, ICAM-3) is a transmembrane glycoprotein expressed by leukocytes, that serves as a counter-receptor for the lymphocyte function-associated antigen (LFA)-1 integrin. Besides functioning as an adhesive molecule that mediates e.g. the contact between T cells and antigen presenting cells, ICAM-3 regulates affinity of LFA-1 for ICAM-1 and induces T cell activation and proliferation. ICAM-3 plays an essential role in the initiation of the immune response both on T cells and antigen presenting cells and interacts also with CD209 (dendritic cell-specific ICAM-3-grabbing nonintegrin, DC-SIGN), a C-type lectin of dendritic cells and macrophages; this process is involved in dialogue between dendritic cells and granulocytes.
