Blockade of Receptor-ligand Interaction
In a functional ELISA, 2-6 µg/mL of this antibody will block 50% of the binding of 5 µg/mL of human IgG to immobilized Recombinant Human Fc gamma  RIIIB/CD16b (Catalog # 1597-FC) coated at 5 µg/mL (100 µL/well). At 50 µg/mL, this antibody will block >90% of the binding.
 

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Data Example

Detection of Human Fc gamma RIII (CD16) by Western Blot. Western blot shows lysates of human spleen tissue, human lung tissue, and human peripheral blood mononuclear cells (PBMC). PVDF membrane was probed with 2 µg/mL of Goat Anti-Human Fc gamma RIII (CD16) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1597) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Fc gamma RIII (CD16) at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Fc gamma RIII (CD16)

Receptors for the Fc region of IgG (Fc gamma R) are members of the Ig superfamily. Based on their genetic organization and molecular structure, three classes of human Fc gamma Rs: RI (CD64), RII (CD32), and RIII (CD16), which generate multiple isoforms, are recognized (1 - 3). These receptors function in the activation or inhibition of immune responses. The activating-type receptor either has, or associates non-covalently with an accessory subunit (FcR gamma or zeta  chain) that has an immunoreceptor tyrosine-based activation motif (ITAM) in its cytoplasmic domain. In contrast, the inhibitory receptor (Fc gamma RIIB) has a built-in immunoreceptor tyrosine-based inhibitory motif (ITIM) in its own cytoplasmic domain. Fc gamma RI is a high-affinity receptor that binds monomeric IgG. Both Fc gamma RII and RIII are low-affinity receptors that bind IgG in the form of immune complexes. Two genes for human Fc gamma RIII, A and B, encoding a transmembrane receptor and a glycosylphosphatidylinositol (GPI) anchored protein, respectively, have been identified. Three allelic variants of Fc gamma RIIIB, NA-1, NA-2, and SH, exist. A soluble form of Fc gamma RIIIB corresponding to the extracellular region of the receptor is produced by proteolytic cleavage and circulates in plasma and other body fluids. The extracellular domains of Fc gamma RIIIA and B share 97% amino acid sequence homology. Whereas Fc gamma RIIIA is expressed on most effector cells of the immune system including macrophage, monocyte, NK cells, mast cells, eosinophils, dendritic cells, and Langerhans cells, Fc gamma RIIIB is selectively expressed in neutrophils and eosinophils. Signaling through Fc gamma RIIIA results in oxidative burst, cytokine release and phagocytosis by macrophages, antibody-dependent cellular cytotoxicity by natural killer cells and degranulation of mast cells. By contrast, Fc gamma RIIIB is a decoy receptor that binds IgG complexes without triggering activation. Soluble Fc gamma RIIIB has a regulatory role in inflammatory processes (4). It interacts with complement receptors CR3 and CR4 on monocytes to induce the production of pro-inflammatory cytokines.
