Description
The 165903 monoclonal antibody specifically recognizes UL16-binding protein 2, 5, and 6 (ULBP-2/5/6). UL16 is a human cytomegalovirus (HCMV) glycoprotein that can bind to human ULBP proteins which share homology with MHC class I proteins. ULBP-2 is also known as RAET1H (retinoic acid early transcript), NKG2DL2 (NKG2D ligand 2), and ALCAN-alpha. ULBP-5 is likewise known as RAET1G whereas ULBP-6 is also referred to as RAET1L. The ULBP-2/5/6 proteins possess only the alpha 1 and alpha 2 Ig-like domains and have no capacity to bind peptides or interact with beta 2 microglobulin. All three proteins can be expressed on the cell surface as glycophosphatidylinositol (GPI)-linked forms whereas ULBP2 and ULBP5 also exist as transmembrane-anchored forms. These proteins may be expressed on various cells types during development or cells experiencing stress caused by high proliferative activity, infection, transformation, or exposure to mediators in inflammatory or autoimmune diseases. The ULBP-2/5/6 proteins can bind to NKG2D and thereby transduce activating signals into NK cells and costimulatory signals into activated CD8+ T cells resulting in enhanced cell-mediated cytotoxicity or cytokine production. The expression of ULBP-2/5/6 proteins on infected or tumor cells can play an important role in immune surveillance and homeostasis.
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.
