. We used flow cytometry immunophenotyping with an antibody panel including CD11a . We then analyzed the cell surface antigen expression on each enzyme-dissociated macrophage sub-population by means of flow cytometry. However, the analysis of the expression profiles of the CD11b and CD45 markers by flow cytometry allows us to distinguish the microglia (CD11b + CD45 med) from the MDM (CD11b + CD45 high). These antibodies target CD11b in Human, Mouse, Baboon, Rhesus Monkey and Cynomolgus Monkey samples. As a control, CD11b antibody staining was omitted and cells were measured in the same channels. (A) Dissociated cells were stained with the specified antibodies and analyzed by flow cytometry using FlowLogic . Flow cytometry can be used to identify mast cells based on their high level expression of CD117/c-kit with variable side scatter, along with expression of IL-3 R alpha/CD123 and Fc epsilon RI.

CD11b is specific for the 165-kilodalton (kDa) subunit of the CD11b/CD18 antigen heterodimer. 1998; 5(5):695-702 . In order to characterize distinct MNP subsets in the kidney, flow cytometric approaches have utilized surface markers CD11b, F4/80, Ly6C, and/or CD11c for distinction of at least three 11,12,13,14 . In this Tech Spotlight, we will demonstrate how various DC subsets in tumor and other tissue-derived cell samples can be analyzed using this panel. To address the growing need for robust comprehensive DC immunophenotyping in murine pre-clinical models, we have configured a new standard panel, CompDC. Basophils have distinct immunophenotypic features by flow cytometry. Three subsets of mouse NK cells have been characterized based on the differential expression of Integrin alpha M/CD11b and CD27. admin@cytometry.org Phone: 847. . Determination of Leukocyte Populations with CD-Markers. Markers associated with "classically activated" "M1-like" macrophages are up-regulated only during the . Flow cytometry was performed with the MACSQuant . In mice, NK cells are defined as CD3 - NK1.1 + or CD3-NKp46 + cells that also typically express Integrin alpha 2/CD49b, Integrin alpha M/CD11b, CD27, T-bet, and Eomes, and lack expression of CD127/IL-7 R alpha. Anti-TMEM119 antibody [28-3] - Microglial marker (ab209064) Mouse: Flow cytometry: Anti-TMEM119 antibody [106-6] - Microglial marker (ab210405) Human: . Rat markers CD11b and CD106 have been used in flow cytometry (Figure 3), showing myeloid cell populations. These scientists methodically dissected the effects of murine IL-6 (mIL-6) on amyloid beta deposition, gliosis, and resultant phagocytic inflammation. In the present study a standardized quantitative flow cytometry assay directly performed in whole blood has been used to determine CD11b expression on PMN cells. Effects of anticoagulants and temperature on expression of activation markers CD11b and HLA-DR on human leukocytes.. Clin Diagn Lab Immunol. A signal cascade is usually initiated, altering the behavior . It is part of Flow Cytometry in Clinical Diagnosis by John Carey, Phil McCoy and David Keren. Page-Shipp L, Tiemessen CT. Our CD11b monoclonal, polyclonal and recombinant monoclonal . When using flow cytometry to determine certain leukocyte population usually a combination of several CD markers is used to determine a subpopulation, since one single marker . CD11b/Mo2/CD45/CD64: myeloid differentiation 9: CD45/PI: . . Flow cytometry analysis of DCs from spleen, lung, and lamina propria. Browse all CD11b antibodies . . Acute promyelocytic leukemia (APL) is an aggressive disease that requires prompt diagnosis and therapy. The CD11b antibody recognizes a human leucocyte antigen that is the C3bi complement receptor (CR3). . Flow cytometry analysis of rat makers CD11b and CD106. Flow cytometric comparison of different clones for CD11b. In order to investigate the differentiation process of monocytes (THP-1) into macrophages induced by PMA, I have measured CD14, CD71 and CD11b expression by flow cytometry. They lack the expression of CD14, CD15, CD16, CD19, CD34, CD64, and CD117 . (Eo771 breast cancer) stained with anti-CD11b (green) . Interesting work from the Mayo Clinic focused on Alzheimer's disease (AD) and used the CD11b antibody for both immunoblotting and flow cytometry experiments (3). basophils express CD11b, dim CD11c, CD13, dim CD22, dim CD25, CD33, and bright CD38. Upon activation granulocytes upregulate several adhesion molecules (CD11b) and granule proteins (CD35, CD66b) and shed surface l-selectin (CD62L).These changes in expression, as assessed by flow cytometry, can be used as markers for activation. . Choose the best markers for microglia, including TMEM119 and Iba1 with this at-a-glance guide. Mutual exclusive markers - CD19 and CD5 stain either one population on another, but never both. Abstract. 3. (CR3). d. After washing, add 12.5 mL of fresh calcium/magnesium-free PBS containing 5 mM EDTA and 2 mM DTT to the 50-mL tubes and incubate at 37C with agitation for 20 min to detach the epithelial cells. The erythroid lineage markers usually analyzed by flow cytometry include CD36 (thrombospondin receptor), CD71 (transferrin receptor), CD235a (glycophorin-A), CD105, . The 95-kDa CD18 antigen, the chain of leucocyte function-associated antigen-1 (LFA-1), is common to the CD11a/CD18 (LFA-1) and CD11c/CD18 antigen heterodimers. e. Mouse spleens, lungs, and small intestines were dissociated with the gentleMACS Octo Dissociator with Heaters and the respective MACS Tissue Dissociation Kit. CD molecules can act in numerous ways, often acting as receptors or ligands (the molecule that activates a receptor) important to the cell. CD11b is specific for the 165-kilodalton (kDa) subunit of the CD11b/CD18 antigen heterodimer. Human peripheral blood cells (PBMCs) after erythrocyte lysis were stained with CD11b antibodies and plotted against the side scatter. Unfortunately, flow cytometry measurement of markers with a continuous distribution loses quantitative meaning outside single experiments as expression is presented as a mean fluorescence . Although the macrophage markers CD64 and MerTK were similarly expressed on all the sub-populations, the expression profile of Tim4, Ly6C, CD11c and MHC class II was different among these sub-populations ().Sub-population I included the population that expressed . In Figure 4 immunofluorescence staining of CD11b alongside CD4 in rat spleen shows macrophages and T cells. Additionally, mast cells express ENPP-3/CD203c, and CD200 R3 in mice, as well as, the transcription factor, MITF, and they lack expression of MHC class II. distinct phenotype (Siglec F high CD11c + CD64 + CD11b ) and can be easily separated from interstitial macrophages and CD11b + DCs, using flow cytometry. . Clinical Diagnostics; . However, the absence of standardized assay and the variability of preanalytical settings leading to PMN artifactual activation have compromised the interest of this marker. Explore more Microglia Markers. Gr1 is an antibody against Ly6G (granulocyte marker) and Ly6C (macrophage marker) - both are of the Ly6 family of GPI anchor proteins. Flow cytometry immunophenotyping can serve as a screening test for APL before the results of cytogenetic or molecular testing for t(15;17)(q22;q21)/PML-RAR are often dimly expressed or absent in APL. They are in the dim CD45/low side scatter area or "blast" gate (figure 1). In this protocol, we show that the density gradient centrifugation and the flow cytometry analysis can be used to characterize these CNS macrophage . Flow Cytometry Reagents. Fig. Hmmm, CD11b is a myeloid marker. The cluster of differentiation ( CD) is a protocol used for the identification and investigation of cell surface molecules present on leukocytes. Antibodies that detect CD11b can be used in several scientific applications, including Flow Cytometry, Immunohistochemistry, Western Blot, Immunoprecipitation and Functional assay. Dysplasia is characterized by maturative asynchronism in the expression of CD10, CD11b, and CD15 on CD34 positive cells, as well as abnormal expression of CD2, .
