Product Details

Purification tag / Conjugate: This FCGR3A protein is labelled with His tag.

Purpose: Recombinant Human CD16a/FCGR3A Protein (176 Val, His Tag)(Active)

Sequence: Met 1-Gln 208

Characteristics: A DNA sequence encoding the extracellular domain (Met 1-Gln 208) of human CD16a (AAH17865.1) was expressed, with a C-terminal polyhistidine tag. It is identical to FCGR3A158F/V in the reference.

Endotoxin Level: < 1.0 EU per μg as determined by the LAL method.

Biological Activity Comment: 1.Using the Octet RED System, the affinity constant (Kd) of CD16a bound to Human IgG1 was 80nM.2.Measured by its binding ability in a functional ELISA. Immobilized human CD16a-His(176 Val) at 10ug/ml(100ul/well ) can bind human IgG1 with a linear range of 0.00128-0.8 μg/ml.

Target Details

Target: FCGR3A (Fc Fragment of IgG, Low Affinity IIIa, Receptor (CD16a) (FCGR3A))

Alternative Name: CD16a/FCGR3A

Background:

Background: The Fc receptor with low affinity for IgG (FCGR3, or CD16) is encoded by 2 nearly identical genes, FCGR3A and FCGR3B, resulting in tissue-specific expression of alternative membrane-anchored isoforms. FCGR3A, it is also known as CD16a, encodes a transmembrane protein expressed on activated monocytes/macrophages, natural killer (NK) cells, and a subset of T cells. CD16a / FCGR3A is a receptor expressed on NK cells that facilitates antibody dependent cellular cytotoxicity (ADCC) by binding to the Fc portion of various antibodies. CD16a / FCGR3A also has a broader function. CD16a / FCGR3A is directly involved in the lysis of some virus-infected cells and tumor cells by NK cells, independent of antibody binding. Cross-linking of CD16a / FCGR3A on NK cells resulted in increased intracellular Ca2+ levels and a cascade of biochemical events similar to those activated by the T cell receptor. CD16a / FCGR3A on human NK cells is a lysis receptor that mediates the direct killing of some virus infected and tumor cells, independent of antibody ligation.
