CD11b antibody | CA16.3E10
CD11b+CD14−MHCII− cells suppress T cell proliferation. Facs sorted CD11b+CD14−MHCII− cells isolated from a dog with osteosarcoma or healthy PBMCs were co-incubated with mitogen-stimulated CD4+ and CD8+ T cells isolated from a healthy dog for 72 hs. No stimulated cells were used as negative control. Proliferative responses were measured by 3H-thymidine incorporation from experiments performed in triplicate. CPM, counts per minute. Mean ± SEM are shown.

CD11b+CD14+MHCII− cells demonstrate ability to suppressive T cell proliferation. (A) CD11b+CD14+MHCII− cells were sorted from peripheral blood sample of an osteosarcoma dog (B) and co-cultured with healthy dog PBMCs in the presence of mitogen for 72 hs. Non-stimulated PBMCs were used as negative control and PBMCs co-cultured with healthy PMNs were used to control for the effect of adding cells to the assay. Proliferative responses were measured by 3H-thymidine incorporation. CPM, counts per minute. The experiment was performed in triplicate. Mean ± SEM are shown.

Staining characteristics and evaluation of two commercially available canine granulocytic antibodies of canine peripheral blood. (a) Cells were analyzed according to forward and side scatter. Cells were either gated to include all live and dead (no gate), all live cells including lymphocytes (R1, lymphocytes are circled) and all myeloid cells (P1). (b) Cells were labeled using canine anti-CD11b and either (a) CADO48A or (b) DH59B with the same concentration of secondary antibody FITC. As can be seen in (a), CADO48A allows visualization of an additional cell population as compared to DH59B (b). These results were repeatable with multiple blood samples from different dogs. The cells in (b) were gated on P1 as indicated in (a).

Optimization of secondary antibody staining concentration for detection of CADO48A. Cells were stained with the primary antibody CADO48A alone followed by (a) 1:10 (b) 1:50 and (c) 1:100 dilutions of a secondary FITC antibody. Optimal detection was seen between 1:50 and 1:100 dilution with CADO48A alone. Secondary FITC concentrations of 1:50 (d) and 1:100 (e) to detect CADO48A on pre-labeled CD11b cells were then evaluated and demonstrated that a 1:50 concentration of FITC was optimal for optimal detection of distinct CADO48A+ cells. Based on these findings, a 1:50 FITC concentration was used in all clinical samples. All cells in these diagrams were gated on P1.

Both EDTA and media samples were kept refrigerated. These findings show a decrease over time of population distinction in EDTA with minimal changes when cells are kept in media up to 48 hours. All cells were gated on P1.

Effects of fixation on CD11b and CADO48A expression levels. Cells were stained for CD11b and CADO48A and evaluated pre-fixation (a) or subsequently fixed with 4% paraformaldehyde at (b) 4 hours, (c) 24 hours), (d) 48 hours or (e) 72 hours post-fixation before analysis on the flow cytometer. Fixation of cells appears to have limited effects on expression levels of CD11b and CADO48A expression up to 24 hours and then only mild increases of 4-6% of CD11b+CADO48A+ cells are seen at 24, 48 and 72 hours post-fixation. All cells seen in this diagram were gated on P1.

Mouse anti Dog CD11b antibody, clone CA16.3E10 is a monoclonal antibody recognizing the canine CD11b cell surface antigen, a member of the alpha integrin family. CD11b forms one of the possible alpha chains of the canine leukocyte adhesion complexes (LeuCAMs), these contain a common 95 kDa β chain (CD18) non-covalently bound to either a 150 kDa (CD11c), 165 kDa (CD11b) or 180 kDa (CD11a) α chain (Moore et al. 1990. The CD11/CD18 complex is also known as the CR3 receptor.
Canine CD11b is expressed by granulocytes, monocytes, NK cells and some macrophages. Mouse anti Dog CD11b antibody, clone CA16.3E10 has been used to evaluate the effect of anesthetic administration of CD11b expression on canine neutrophils (Maeda et al. 2010) demonstrating attenuation of CD11b expression at high concentrations administered lidocaine hydrochloride and reduced adhesion of neutrophils to endothelium.
