CD200 Monoclonal Antibody (OX104), NovaFluor™ Red 710, eBioscience™, Invitrogen™

Beskrivning

The monoclonal antibody OX104 recognizes human CD200 also known as OX2. CD200 is a member of the Ig superfamily with 2 Ig domains, a transmembrane and cytoplasmic domain. CD200 is expressed on resting and activated B cells, a subset of resting and activated T cells, keratinocytes, peripheral and central nerve cells, follicular dendritic cells and ovarian cells. The interaction with CD200R results in macrophage activation (IL-6 production), inhibition of mast cell degranulation along with reduced TNFalpha and IL-13 secretion and overall attenuation of the activation status of lymphocytes. A role has also been suggested in maternal tolerance as expression of CD200 is also present on the trophoblast. Applications Reported: This OX104 antibody has been reported for use in flow cytometric analysis. Applications Tested: This OX104 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. This may be used at less than or equal to 0.06μg per test NovaFluor dyes are not compatible with DNA intercalating viability dyes.

CD200 is a type-1 membrane glycoprotein that contains two immunoglobulin domains, and belongs to the immunoglobulin superfamily. CD200 is a broadly distributed cell surface glycoprotein that interacts with a receptor on myeloid cells (CD200R) and is implicated in locally preventing macrophage activation. Distant, but recognizable, homologues of CD200 have been identified in many herpesviruses and poxviruses. Studies of the related genes in mouse and rat suggest that CD200 may regulate myeloid cell activity and delivers an inhibitory signal for the macrophage lineage in diverse tissues. Multiple alternatively spliced transcript variants that encode different isoforms of CD200 have been found. Diseases associated with CD200 dysfunction include Mantle Cell Lymphoma and Primary Hypertrophic Osteoarthropathy.
