CD195 (CCR5) Mouse anti-Human, PE, Clone: eBioT21/8 (T21/8), eBioscience™
Mouse Monoclonal Antibody
Manufacturer: Invitrogen 12195742
Description: The eBioT21/8 monoclonal antibody reacts with the amino terminus of human CCR5 (CD195), an approximately 45 kDa member of the G protein-coupled receptor (GPCR) superfamily that binds chemokines including MIP-1alpha, MIP-1beta and RANTES. Human CCR5 is expressed on resting T cells with a memory/effector phenotype, monocytes, macrophages and immature dendritic cells. CCR5 functions as a receptor to direct the chemotaxis of lymphocytes, and is the primary co-receptor for macrophage-tropic Human Immunodeficiency Virus Type 1 (HIV-1), which binds CCR5 through gp120. Binding of the eBioT21/8 monoclonal antibody displays donor variability and may be affected by sub-optimal staining conditions. Applications Reported: This eBioT21/8 (T21/8) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBioT21/8 (T21/8) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. For optimal performance, it is recommended that staining with eBioT21/8 be done at room temperature or 37°C for 1 hour in Flow Cytometry Staining Buffer (cat. 00-4222). This can be used at 5 µL (0.125 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, Green Laser, Yellow-Green Laser. Filtration: 0.2 μm post-manufacturing filtered. Human immunodeficiency virus (HIV) and related virus require coreceptors, in addition to CD4, to infect target cells. Some G protein-coupled receptors including CCR5, CXCR4, CCR3, CCR2b and CCR8 in the chemokine receptor family, and four new human molecules GPR15, STRL33, GPR1 and V28 were recently identified as HIV coreceptors. Among them, CCR5 (CC-CKR-5) is a principal coreceptor for macrophage- and dual-tropic HIV-1 strains fusion and entry of human white blood cells. CCR5 is required for the infection by HIV-1, HIV-2, and SIV. The beta-chemokines RANTES, MIP-alpha and MIP-beta are the ligands for CCR5 and prevent infection by M-tropic HIV-1. CXC5 associates with the surface CD4-gp120 of HIV complex and leads to membrane fusion and virus entry of target cells. The amino-terminal domain and the extracellular loops of CCR5 serve as HIV biding sites. CCR5 messenger RNA is expressed in lymphoid organs and monocytes.
