Applications and Data

	Recommended Concentration	Sample
Western Blot	0.1 µg/mL	Recombinant Human Fc gamma  RIIB/C (CD32b/c) (Catalog # 1875-CD)
Flow Cytometry	2.5 µg/106 cells	Human peripheral blood cells
Blockade of Receptor-ligand Interaction	In a functional ELISA, 2-6 µg/mL of this antibody will block 50% of the binding of 2 μg/mL of human IgG to immobilized Recombinant Human Fc gamma RIIB/C (CD32b/c) (Catalog # 1875-CD) coated at 2 µg/mL (100 µL/well). At 100 μg/mL, this antibody will block >90% of the binding.
CyTOF-ready	Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Immunocytochemistry

Fc gamma  RII/CD32 in Human PBMCs. Fc gamma  RII/CD32 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human Fc gamma  RII/CD32 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1330) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasmic. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Long Name	Fc gamma Receptor II
Entrez Gene IDs	2212 (Human); 14130 (Mouse)
Background	Fc gamma RII/CD32
background_content	Background: Fc gamma RII/CD32 Receptors for the Fc region of IgG (Fc gamma Rs) are members of the Ig superfamily that function in the activation or inhibition of immune responses such as degranulation, phagocytosis, ADCC (antibody-dependent cellular toxicity), cytokine release, and B cell proliferation (1‑3). The Fc gamma Rs have been divided into three classes based on close relationships in their extracellular domains; these groups are designated Fc gamma  RI (also known as CD64), Fc gamma  RII (CD32), and Fc gamma  RIII (CD16). Each group may be encoded by multiple genes and exist in different isoforms depending on species and cell type. The CD64 proteins are high affinity receptors (~10-8‑10-9 M) capable of binding monomeric IgG, whereas the CD16 and CD32 proteins bind IgG with lower affinities (~10-6‑10-7 M) only recognizing IgG aggregates surrounding multivalent antigens (1, 4). Fc gamma Rs that deliver an activating signal either have an intrinsic immunoreceptor tyrosine-based activation motif (ITAM) within their cytoplasmic domains or associate with one of the ITAM-bearing adapter subunits, FcR gamma or zeta (3, 5). The only inhibitory member in human and mouse, Fc gamma  RIIB, has an intrinsic cytoplasmic immunoreceptor tyrosine-based inhibitory motif (ITIM). The coordinated functioning of activating and inhibitory receptors is necessary for successful initiation, amplification, and termination of immune responses (5). Three distinct genes encode the human CD32 group, and the protein products are designated Fc gamma  RIIA, B, and C (1). These receptors are glycoproteins of approximately 40 kDa having two extracellular Ig-like domains. The Fc gamma  RII proteins share 94‑99% amino acid identity in their extracellular domains but differ substantially in their transmembrane and cytoplasmic domains. Fc gamma  RIIA associates with FcR gamma, and delivers an activating signal upon ligand binding (3, 5). In contrast, Fc gamma  RIIB delivers an inhibitory signal. Fc gamma  RIIC represents an unequal cross-over event between the IIA and IIB genes. Its extracellular domain shares 99% amino acid identity with Fc gamma  RIIB, but a portion of the cytoplasmic domain is closely related to Fc gamma  RIIA. Fc gamma  RII proteins are expressed on cells of both myeloid and lymphoid lineages as well as on cells of non-hematopoietic origin.
