Description
The BB7.1 monoclonal antibody specifically recognizes the Human Leukocyte Antigen-B7 (HLA-B7) alpha subunit. The HLA-B7 alpha chain can noncovalently heterodimerize with β2-microglobulin to form a Major Histocompatibility Complex (MHC) class I B7 antigen that is involved in antigen presentation to CD8+ T cells or might serve as an NK cell receptor ligand. HLA-B7 is a serotype that identifies the more common HLA-B (HLA-B*07) encoded gene products which are expressed on nearly all nucleated cells of HLA-B7-positive individuals. B7 is a risk factor for cervical cancer, sarcoidosis, and some spondylarthropathies. The BB7.1 antibody can be used to distinguish false HLA-B27-positve staining when used in conjunction with some HLA-B27 antibodies that crossreact with HLA-B7. Although highly specific, the BB7.1 antibody can reportedly crossreact with HLA-B42 and HLA-B81 antigens.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).
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 BUV661 under optimal conditions that minimize unconjugated dye and antibody.
1. This antibody was developed for use in flow cytometry.
2. 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.
3. Researchers should determine the optimal concentration of this reagent for their individual applications.
4. An isotype control should be used at the same concentration as the antibody of interest.
5. 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.
