Description
The 6F12 antibody reacts with a 7-transmembrane-domain protein, which is similar to the F4/80 macrophage antigen of the EGF-TM7 protein family and is encoded by the Emr4 gene. The FIRE protein is expressed on myeloid cells with a denditic cell (DC) developmental potential, including subsets of DC and macrophages in the spleen and lymph nodes, most resident peritoneal macrophages, many peripheral blood monocytes, and a subpopulation of bone-marrow myeloid-cell progenitors. The protein is not detected on peripheral T and B lymphocytes, and it is down-regulated on thioglycollate-elicited peritoneal macrophages and on dendritic cells activated by GM-CSF, IFN-γ, anti-CD40, and LPS. Using soluble biotinylated fusion protein, a FIRE ligand was detected on a mouse IgG+ B lymphoma cell line (A20), but not on myeloid, fibroblast, or T-cell lines, suggesting that the FIRE protein may be involved in immunoregulatory interactions between antigen-presenting cells and B lymphocytes.
For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).
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 BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
4. 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.
