Description: This BM16 monoclonal antibody reacts with human CD294, which is also known as G protein-coupled receptor-44 (GPR-44) or chemoattractant receptor expressed on Th2 cells (CRTH2). CD294 is expressed on Th2 cells, some CD8+ cells, eosinophils, and basophils. Moreover, CD294 binds prostaglandin D2, which promotes leukocyte chemotaxis during allergic responses. CD294 has been reported to mediate prostaglandin D2-mediated suppression of apoptosis of Th2 cells by activating the PI3K pathway.
Applications Reported: This BM16 antibody has been reported for use in flow cytometric analysis.
Applications Tested: This BM16 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.
Filtration: 0.2 µm post-manufacturing filtered.
The prostaglandin D2 receptor 2 (PTGDR2), also known as CRTH2, is expressed on Th2 cells and eosinophils and mediates chemotaxis of these cells to PGD2 and is thus thought to be a key receptor mediating eosinophil and Th2 recruitment during allergic responses. However, PTGDR2-null mice showed enhanced eosinophil recruitment into the lung consistent with observations that the PTGDR2-null mice produced significantly higher amounts of interleukin-5 (IL-5) and IL-3. This suggests that PTGDR2 plays a nonredundant role in restricting eosinophilia and allergic response in vivo.
