Fc gamma RIIIA/CD16a Protein, Human (F176V, CHO, His)

Cat. No.: HY-P75210
Handling Instructions

Fc gamma RIIIA/CD16a Protein, a receptor for the Fc fragment of IgG, activates antibody-dependent cellular cytotoxicity (ADCC) upon binding antigen-IgG complexes. It mediates IgG effector functions on NK cells, generating memory-like adaptive NK cells for efficient virus-infected cell elimination. Fc gamma RIIIA/CD16a regulates NK cell survival, proliferation, and prevents progenitor apoptosis. It forms signaling complexes, driving intracellular cascades for NK cell activation. The protein plays a crucial role in antitumor activities, triggering TNFA-dependent ADCC. In Dengue virus infection, it contributes to pathogenesis via antibody-dependent enhancement (ADE). Fc gamma RIIIA/CD16a Protein, Human (F176V, CHO, His) is the recombinant human-derived Fc gamma RIIIA/CD16a protein, expressed by CHO , with C-His labeled tag and F176V mutation. The total length of Fc gamma RIIIA/CD16a Protein, Human (F176V, CHO, His) is 192 a.a., with molecular weight of 40-45 kDa.

Background

Fc gamma RIIIA/CD16a Protein serves as a receptor for the invariable Fc fragment of immunoglobulin gamma (IgG), optimally activated upon binding clustered antigen-IgG complexes displayed on cell surfaces, initiating antibody-dependent cellular cytotoxicity (ADCC). This process involves the lysis of antibody-coated cells, preventing inappropriate effector cell activation in the absence of an antigenic trigger. The protein mediates IgG effector functions on natural killer (NK) cells, binding antigen-IgG complexes generated during infection to trigger NK cell-dependent cytokine production and degranulation. Fc gamma RIIIA/CD16a is crucial in generating memory-like adaptive NK cells that efficiently eliminate virus-infected cells via ADCC. It regulates NK cell survival, proliferation, and prevents NK cell progenitor apoptosis. As an Fc-binding subunit, it associates with CD247 and/or FCER1G adapters to form functional signaling complexes, leading to intracellular signaling cascades that drive NK cell activation. The protein also plays a role in mediating the antitumor activities of therapeutic antibodies, triggering TNFA-dependent ADCC of IgG-coated tumor cells and enhancing ADCC in response to afucosylated IgGs. In the context of Dengue virus infection, Fc gamma RIIIA/CD16a is involved in pathogenesis through an antibody-dependent enhancement (ADE) mechanism, facilitating virus entry into myeloid cells and subsequent viral replication during secondary infections.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
