Description
The S-HCL-3 monoclonal antibody specifically binds to CD11c which is also known as Integrin alpha X (Integrin αX), Complement component 3 receptor 4 subunit or CR4. CD11c is a ~150 kDa type I transmembrane glycoprotein that is encoded by ITGAX (integrin subunit alpha X). CD11c (Integrin αX) is expressed on dendritic cells, monocytes, macrophages, granulocytes, NK cells and subsets of B and T cells. CD11c (Integrin αX) is also present on hairy cell leukemias (HCL) and on some acute myeloid leukemias (AML). The S-HCL-3 antibody stains sinus histiocytes of lymph node, tonsil, and spleen; macrophages in the cortex and medulla of thymus; Kupffer cells in liver; elongated intertubular cells in kidney; and alveolar macrophages in lung tissue. In malignant tissue, the antibody stains true histiocytic lymphomas; it does not stain carcinomas or T or B lymphomas. CD11c (Integrin αX) associates with CD18 (ITGB2/Integrin beta-2) to form the CD11c/ CD18 heterodimer which is likewise known as Leukocyte adhesion receptor p150,95 or Complement receptor type 4 (CR4). Ligands for this heterodimeric adhesion receptor include fibrinogen, iC3b, CD23, and CD54 (ICAM-1).
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application. 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 to the dye under optimum conditions that minimize unconjugated dye and antibody.
1. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
2. Researchers should determine the optimal concentration of this reagent for their individual applications.
3. An isotype control should be used at the same concentration as the antibody of interest.
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.
