Questions? Please consult our answers to frequently asked questions at http://www.ebioscience.com/faq. DescriptionThe eBio5E8-G9-B4 monoclonal antibody reacts with human CD193 (CCR3, CKR3). CD193 is a member of the seven transmembrane G-protein coupled receptor (GPCR) family, and is a high affinity chemokine receptor for the chemokines eotaxin-1 (CCL11), eotaxin-2 (CCL24), eotaxin-3 (CCL26) and MCP-4 (CCL13), but has also been reported to bind RANTES, MCP-3 and MCP-4. CD193 is highly expressed on the surface of eosinophils, and is the key eosinophil chemokine receptor responsible for the regulation of eosinophil migration and function. In addition to eosinophils, CD193 is also expressed on CD4+ TH2 cells, basophils, mast cells, mononuclear phagocytes, platelets, CD34+ hematopoietic progenitors and airway epithelial cells. CD193 likely plays an important role in the migration of eosinophils in allergic airway inflammation and asthma. CD193 can also serve as a receptor for HIV-1 cell entry. Applications ReportedFor research use only, not for diagnostic or therapeutic use. This eBio5E8-G9-B4 (5E8-G9-B4) antibody has been reported for use in flow cytometric analysis. Applications TestedThis eBio5E8-G9-B4 (5E8-G9-B4) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood. This can be used at 20 μl (0.25 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume). References
