Image caption:
CD11b surface expression and CD11b-dependent-NET formation of bovine E. bovis sporozoite-exposed PMN. (A) Bovine PMN were exposed to CFSE-labeled sporozoites (1:1) and subjected to FACS analysis probing with an antibody directed against CD11b. Non-exposed PMN in plain medium served as negative controls. The histograms represent the shift in the mean fluorescence of the PMN population analyzed and are representative of the experiments performed. (B) NET formation in the presence of anti-CD11b antibodies. Bovine PMN were pre-treated with anti-CD11b prior to sporozoite exposure. Stimulation with zymosan served as a positive control; PMN in plain medium were used for negative controls.

Gating Strategy forFlow Cytometry:
More that 10,000 events were acquired ba a Macsquant flow cytometer for each sample and analysed with Flowlogic software using the following strategy.
The main cell population was selected using side scatter - Area (SS-A) versus FSC-A in P1 gate. Doublet cells were excluded in gate P2. Cells from P1/P2 gate were analsed for the specific staining as shown in histogram overlays showing staining with specific antibodies (in red) in comparison with their respective isotypes (in blue). Markers (M, M1, M2, M3, M4, M5) were set up according to the control isotypes to determine the percentage of positive cells. The same strategy was applied to all samples.

FITC conjugated Mouse anti Bovine CD11b antibody, clone CC126 (MCA1425F) used for the analysis of CD11b expression on ovine and bovine cells by flow cytometry.
Image caption:
Identification of neonatal intestinal mononuclear phagocytes in the ileal Peyer’s patch of lambs and calves. Intestinal tissues from the ileal Peyer’s patch (IPP) were recovered from 10-day-old lambs (n = 6) and calves (n = 10). Mechanical and enzymatic dissociations were performed to obtain total isolated intestinal cells, then stained for flow cytometry. Representative gating for mononuclear phagocytes (MP) subsets are shown for the IPP of lamb (A) and calf (B). Following exclusion of dead cells, CD11c+MHCII+ cells were gated to select total MP and then four subsets were distinguished based on surface expression of CD14, CD172α, CD11b, and Cadm1: CD14+CD172α+Cadm1intCD11b+ (subset 1, green), CD14−CD172α−Cadm1+CD11b− (subset 2, purple), CD14−CD172α+Cadm1intCD11b+ (subset 3, blue), and CD14−CD172α+/-Cadm1−CD11b− (subset 4, yellow). Subsets 1, 2, and 3 of MP from the IPP of a 10-day-old lamb were cell sorted by flow cytometry, cytospined, and stained with hematoxylin and eosin. Pictures of the three subsets of MP were obtained by optical microscopy (A, right panel). Pie charts represent the cell proportions in percentage of each intestinal MP subset among viable CD11c+MHCII+ cells (mean ± SD) for lambs (n = 6; A, bottom panel) and calves (n = 10; B, bottom panel).

Filter by Application:
F BA IF WB ResetMouse anti-Bovine CD11b antibody, clone CC126 is a monoclonal antibody raised in mouse that recognizes the bovine CD11b cell surface antigen. The antibody may show cross-reactivity with goat and sheep species. Clone CC126 is validated for Immunohistology – Frozen, Flow cytometry and Immunoprecipitation. CD11b (integrin αM, ITGAM) is a ~165 kDa cell‑surface adhesion molecule that heterodimerizes with CD18 to form Mac‑1 (complement receptor 3, CR3). It is expressed on monocytes, macrophages, granulocytes, activated lymphocytes, subsets of NK and dendritic cells, and microglia. CD11b expression increases during monocyte differentiation, varies among macrophage populations, and is widely used as a myeloid and microglial marker. Dysregulated CD11b has been linked to immune‑mediated disorders such as systemic lupus erythematosus. |
