Invitrogen™ CD193 (CCR3) Monoclonal Antibody (eBio5E8-G9-B4 (5E8-G9-B4)), PE, eBioscience™

Descripción

Description: The 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 Reported: This eBio5E8-G9-B4 (5E8-G9-B4) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBio5E8-G9-B4 (5E8-G9-B4) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.06 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. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser,...

CCR3 (C-C chemokine receptor type 3) binds to eotaxin, eotaxin-3, MCP-3, MCP-4, RANTES, and MIP-1 delta. CCR3 trasnduces a signal by increasing the intracellular calcium ions level. It also serves as an alternative co-receptor with CD4 for HIV-1 infection. Other chemokines play important roles in inflammation and are critical for the recruitment of effector immune cells to sites of infection. Chemokines activate leukocytes by binding to G protein coupled receptors. The ever-growing chemokine receptor subtypes can be divided into 2 major groups, CXCR and CCR, based on the 2 major classes of chemokines.
