CD11b, eFluor 660, clone: M1/70, eBioscience™

Description

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. It probably recognizes the RGD peptide in C3b. CD11b is also a receptor for fibrinogen, factor X, and ICAM1. It recognizes P1 and P2 peptides of fibrinogen gamma chain. The Mac1 CD11b antigen is present on macrophages, granulocytes, natural killer cells, and blood monocytes. CD11b is expressed on 8% of spleen cells, 44% of bone marrow cells, and less than 1% of thymocytes, and is commonly used as a microglial marker in nervous tissue.

Description: The M1/70 monoclonal antibody reacts with mouse CD11b, the 165-170kDa integrin alphaM. CD11b non-covalently associates with CD18 to form alphaM-beta2 integrin (Mac-1) and binds to CD54 (ICAM-1), C3bi, and fibrinogen. Mac-1 is expressed by macrophages, NK cells, granulocytes, activated lymphocytes and mouse B-1 cells in the peritoneal cavity. M1/70 is also cross-reactive to human CD11b, and can be used for the detection of this antigen on human peripheral blood monocytes, granulocytes, and a subset of NK cells. Through interactions with its ligands, CD11b participates in adhesive cell interactions.Applications Reported: This M1/70 antibody has been reported for use in flow cytometric analysis, and immunohistochemical staining of frozen tissue sections.Applications Tested: This M1/70 antibody has been tested by flow cytometric analysis of mouse bone marrow cells. This can be used at less than or equal to 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. The M1/70 antibody has been tested by immunohistochemistry of frozen tissue and can be used at less than or equal to 5 ug/mL. The M1/70 antibody is not recommended for immunohistochemistry of formalin-fixed paraffin embedded tissue. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.eFluor™ 660 is a replacement for Alexa Fluor™ 647. eFluor™ 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser.Filtration: 0.2μm post-manufacturing filtered.
