Description
The 11A3 monoclonal antibody specifically recognizes macrophage inflammatory protein-1α (MIP-1α), a member of the CC chemokine family of proteins. It is produced by T cells, B cells, Langerhans cells, neutrophils and macrophages. MIP-1α plays a role as an inhibitor of stem cell proliferation and as a chempattractant of B cells, eosinophils and cytotoxic T cells. Clone 11A3 also cross-reacts with an intracellular component of rhesus and cynomolgus macaque-LPS-stimulated peripheral blood monocytes. The reactivity pattern observed on CD14-positive cells is similar to that seen on normal human peripheral blood monocytes.
The PE Mouse Anti-Human MIP-1α (CCL3) can be used for multicolor immunofluorescent staining and flow cytometric analyses to identify and enumerate MIP-1α (CCL3) producing cells with mixed cell populations. For optimal immunofluorescent staining with flow cytometric analysis, this anti-cytokine antibody should be titrated (≤ 0.5 µg mAb/million cells). A useful control for demonstrating specificity of staining is either of the following: 1) pre-block the conjugated 11A3 antibody with ligand (e.g., recombinant human MIP-1α (CCL3)) prior to staining, or 2) pre-block the fixed/permeabilized cells with unlabeled 11A3 antibody prior to staining. The intracellular staining technique and use of blocknig controls are described in detail by C. Prussin and D. Metcalfe. A suitable mouse IgG2a, κ isotype control immunoglobulin for assessing the level of background staining on paraformaldehyde-fixed/saponin-permabilized human cells is PE Mouse IgG2a, κ Isotype Control (Cat. No. 554648); use at comparable concentrations to antibody of interest (e.g., ≤0.5 µg mAb/1 million cells).
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. An isotype control should be used at the same concentration as the antibody of interest.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
