Mouse anti Integrin alpha 6BCatalog number: MUB0905P
Integrins are a family of heterodimeric membrane glycoproteins consisting of non-covalently associated α and β subunits. More than 18 α and 8 β subunits with numerous splice variant isoforms have been identified in mammals. In general, integrins function as receptors for extracellular matrix proteins. Certain integrins can also bind to soluble ligands or to counter-receptors on adjacent cells, such as the intracellular adhesion molecules (ICAMs), resulting in aggregation of cells. Signals transduced by integrins play a role in many biological processes, including cell growth, differentiation, migRation and apoptosis. For integrin subunits α3 and α6, two cytoplasmic variants, A and B, have been identified.
6B4 is a Mouse monoclonal IgG1, κ antibody derived by fusion of SP2/0 Mouse myeloma cells with spleen cells from a BALB/c Mouse immunized with a synthetic peptide corresponding to a 34 amino acid stretch in the cytoplasmic domain of integrin α6B including an appending N-terminal cysteine: CSRYDDSVPRYHAVRIRKEEREIKDEKYIDNLEKK coupled to keyhole limpet hemocyanin.
Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.
Formulation: Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.
6B4 recognizes specifically the cytoplasmic domain of integrin subunit α6B. 6B4 stains the basement membrane zone of ducts and acini of salivary gland, kidney tubules, epithelium of colonic crypts and weakly stains sweat glands and sebaceous glands.
Species Reactivity: A broad species reactivity is expected because of the conserved nature of the epitope.
6B4 is suitable for immunoblotting, immunocytochemistry and immunohistochemistry on frozen tissues. Optimal antibody dilution should be determined by titration; recommended range is 1:50 – 1:100 for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent, and 1:100 – 1:500 for immunoblotting applications.
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.
