CD11b antibody | ED8
Lithium inhibits lipopolysaccharide (LPS)-induced microglial activation. Primary microglial cells were pretreated with LiCl at 0.3, 1 and 3 mM for 30 minutes and then stimulated with LPS at 10 ng/ml for 24 hours. (a) and (b) For flow cytometric analysis, the cells were incubated with PE-conjugated ED8 antibody at 37°C for 1 hour. **P <0.01 versus the response to medium alone. #P <0.05, ##P <0.01 versus LPS treatment groups. The data are presented as the mean ± s.e.m. of three independent experiments. (c) The cells were stained with ED8 antibody and upregulated ED8-immunopositive expression (green) on the activated microglia was observed using confocal scanning. The blue staining represents DAPI. Scale bar 50 μm.

Mouse anti Rat CD11b antibody, clone ED8 used for the evaluation of CD11b expression on spinal cord mononuclear cells by flow cytometry.
Image caption:
Aging increases the number of all spinal cord mononuclear cells, and CD45 int/hi CD11b+ nonlymphoid cells, recovered on the 7 th d.p.i. from AO rat spinal cord. (a) Bar graph indicates the total number of mononuclear cells (MNC) isolated from spinal cord of young and aged rats on the 7 th d.p.i. (Panel b) Flow cytometry density plots indicate the expression of CD45 on CD11b+ cells from spinal cord of (left) young and (right) aged rats on the 7 th d.p.i. CD11b + cells were gated as shown in the flow cytometry histograms. Numbers in the flow cytometry histograms represent the percentage of CD11b+ cells. R1 = CD11b+ CD45 hi cells; R2 = CD11b+ CD45 int cells. Numbers in the table indicate the percentage of cells in the specified region (R). Bar graph indicates the number of CD11b+ cells in spinal cords from young and aged rats. (Panel c) Bar graphs indicate the number of (left) CD11b+ CD45 int and (right) CD11b+ CD45 hi cells in spinal cords from young and aged rats on the 7 th d.p.i. (d) Bar graph indicates the fold change in expression of mRNA for SOCS1 in spinal cord mononuclear cells from aged relative to young rats on the 7 th d.p.i. as determined by RT-qPCR. Data are normalized to β-actin (ACTB). All results are presented as means ±SEM (n = 9/group). Data are representative of one of two experiments with similar results. *p <0.05; ***p < 0.001

Mouse anti Rat CD11b antibody, clone ED8 recognizes a membrane antigen on rat macrophages, monocytes, dendritic cells and granulocytes. It also recognizes small ramified microglia in the central nervous system. No other cell types are positive for ED8. The recognized antigen is a heterodimer consisting of ~160 and ~95 kDa, belonging to the family of adhesion molecules CD11b/CD18, also designated as Mac-1 antigen or CR3. Mouse anti Rat CD11b antibody, clones ED7 (MCA618R) and ED8 may recognize closely related epitopes on the same molecule. Both clones ED7 and ED8 induce homotypic aggregation of granulocytes (Drasković-Pavlović et al. 1999).
