Blockade of Receptor-ligand Interaction
In a functional ELISA, 0.1-0.4 µg/mL of this antibody will block 50% of the binding of 75 ng/mL of biotinylated Laminarin to immobilized Recombinant Human Dectin-1/CLEC7A (Catalog # 1859-DC) coated at 250 ng/mL (100 µL/well). At 3 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.
Dectin‑1/CLEC7A in Human Dendritic Cells. Dectin‑1/CLEC7A was detected in immersion fixed mature human dendritic cells using Mouse Anti-Human Dectin‑1/CLEC7A Monoclonal Antibody (Catalog # MAB1859) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (yellow; Catalog # NL007) and counterstained with DAPI (blue).

Dectin-1, also known as CLEC7A and the beta -glucan receptor, is a 33 kDa type II transmembrane C-type lectin that participates in the innate immune response to fungal pathogens. Although Dectin-1 structurally resembles other CLEC molecules, it binds its ligands in a calcium-independent manner (1, 2). Mature human Dectin-1 consists of a short N-terminal ITAM-containing cytoplasmic tail, a transmembrane segment, and a C-terminal stalk with a carbohydrate recognition domain (CRD) in the extracellular domain (3, 4). Alternate splicing generates one major splice form that lacks the stalk region (3‑5). This isoform is expressed on the surface of monocytes, macrophages, myeloid DC, neutrophils, eosinophils, B cells, and CD4+ T cells (6). The CRD selectively binds beta -glucan polymers, a major component of yeast and mycobacterial cell walls (5‑7). Yeast beta -glucan is accessible to Dectin‑1 only during the process of cell budding. Dectin-1 does not recognize the filamentous form of yeast (8). Dectin-1 mediates the phagocytosis of zymosan particles and intact yeast (8‑10). In the membrane, Dectin-1 colocalizes with TLR2 in the presence of zymosan, and the two receptors cooperate in ligand recognition and the propagation of proinflammatory signaling (9, 11‑13). Dectin-1 also interacts with tetraspanin CD37. This increases its stability on the cell membrane and inhibits ligand-induced signaling (14). Dectin-1 knockout mice show increased susceptibility to pathogenic infection (15‑16). The CRD of human Dectin-1 shares 77%, 60%, and 60% amino acid (aa) sequence identity with that of bovine, mouse and rat Dectin-1, respectively. It shares 29%‑39% aa sequence identity with the CRD of other subgroup members, including CLEC-1, CLEC-2, CLEC9A, CLEC12B, LOX-1, and MICL.
