Description: This 15E2 monoclonal antibody reacts with human and non-human primate CD369, which is also known as the Dectin-1 or beta-glucan receptor or CLEC7A. CD369 is expressed predomitly on monocytes, macrophages, and dendritic cells. Moreover, this receptor can also be detected on neutrophils and lymphocytes, as well as induced by cytokines such as IL-4 or LPS. In humans, CD369 exists as two isoforms that arise due to alternative splicing. CD369 binds beta-1,3-glucan and plays an important role in activating signal transduction involved in the innate immune response to fungal and mycobacterial infections. Studies have also shown the involvement of CD369 in dendritic cell activation. The 15E2 monoclonal antibody has been reported to recognize both isoforms of CD369 and activate dendritic cells. It does not crossreact to mouse CD369. Applications Reported: The 15E2 antibody has been reported to activate dendritic cells. Applications Tested: This 15E2 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Endotoxin: Less than 0.001 ng/ug antibody as determined by the LAL assay. Storage and handling: Use in a sterile environment. Filtration: 0.2 µm post-manufacturing filtered. Purity: Greater than 90%, as determined by SDS-PAGE. Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay. Aggregation: Less than 10%, as determined by HPLC. CLEC7A, also known as dectin-1, is a member of the C-type lectin/C-type lectin-like domain (CTL/CTLD) superfamily and is predomitly expressed on myeloid cells. It is a small glycoprotein type II membrane receptor with an extracellular C-type lectin-like domain fold and a cytoplasmic domain with an immunoreceptor tyrosine-based activation motif (ITAM). CLEC7A functions as a pattern-recognition receptor that recognizes a variety of beta-1,3-linked and beta-1,6-linked glucans from fungi and plants, and in this way plays a role in innate immune response. Upon fungal exposure, CLEC7A activates Syk tyrosine kinase, triggering a massive oxidative burst through the formation of reactive oxygen species.
