Catalog No. 50-112-9365

Description

Description: This OX42 monoclonal antibody reacts with rat CD11b and CD11c. CD11b, also known as integrin alpha M or Mac-1, is a component of complement receptor 3 (CR3). CD11c, also known as integrin alpha X, is a component of complement receptor 4 (CR4). CD11b and CD11c are expressed on immune cells such as macrophages, monocytes, granulocytes, and dendritic cells. OX42 has also been shown to detect microglia in the brain, as well as cells of the liver and epidermis. The OX42 antibody has been reported to inhibit complement-mediated rosette formation by granulocytes and macrophages. Moreover, studies demonstrate that OX42 can inhibit granulocyte aggregation. Applications Reported: This OX42 antibody has been reported for use in flow cytometric analysis. Applications Tested: This OX42 antibody has been tested by flow cytometric analysis of rat splenocytes. This can be used at less than or equal to 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. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 μm post-manufacturing filtered.

Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. CD11b is implicated in various adhesive interactions of monocytes, macrophages and granulocytes as well as in mediating the uptake of complement coated particles. It is identical to CR3, the receptor for the iC3b fragment of the third complement component. CD11b is also a receptor for fibrogen, factor X and ICAM1. It recognizes P1 and P2 peptides of fibrogen gamma chain. The Mac1 CD11b antigen is present on macrophages, granulocytes, natural killer cells, blood monocytes. CD11b is expressed on 8% spleen cells, 44% bone marrow cells and less than 1% thymocytes and is commonly used as a microgial marker in nervous tissue. CD11c encodes the integrin alpha X chain protein. This protein combines with the beta 2 chain (ITGB2) to form a leukocyte-specific integrin referred to as inactivated-C3b (iC3b) receptor 4 (CR4). The alpha X beta 2 complex seems to overlap the properties of the alpha M beta 2 integrin in the adherence of neutrophils and monocytes to stimulated endothelium cells, and in the phagocytosis of complement coated particles. Mutations affecting the CD11b/c gene lead to systemic lupus erythematosus 6.
