Description
The 346-11A monoclonal antibody specifically recognizes an epitope at the beginning of the cysteine-rich repeat region of the 200-kDa integrin β4 chain (CD104), which is found on the cell surface as a heterodimeric complex with the integrin α6 chain (CD49f). The α6β4 (CD49f/CD104) complex binds to laminins and is expressed on the basal surface of a variety of epithelial cell types, particularly on stratified squamous epithelia, and is also found in peripheral nerves, in certain subsets of endothelial cells, and on immature thymocytes. It has also been identified on a number of tumor tissues and participates in tumor progression events. Localization of both human and mouse epidermal α6β4 integrin to hemidesmosomes suggests that this heterodimer plays a role in epidermal adhesion to the basement membrane.
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.
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. Researchers should determine the optimal concentration of this reagent for their individual applications.
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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
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.
