• Product name
    Anti-TCR V beta 5 antibody [MEM-262]
  • Description
    Mouse monoclonal [MEM-262] to TCR V beta 5
  • Host species
  • Specificity
    The antibody recognizes beta chains of the TCR expressed by HPB-ALL cell line [carrying V(beta5.3)] and a small subset of peripheral blood T cells. This subset is larger than that recognized by other V(beta5.3)-specific antibodies.

Application Abreviews Notes
Flow Cyt
  • Application notes
    Flow Cyt: Use at an assay dependent dilution.
    IP: Use at an assay dependent dilution.
    WB: Use at an assay dependent dilution. Uniquely recognizes denatured TCR beta chains under the conditions of Western blotting.

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Relevance
      T cell receptors recognize foreign antigens which have been processed as small peptides and bound to major histocompatibility complex (MHC) molecules at the surface of antigen presenting cells (APC). Each T cell receptor is a dimer consisting of one alpha and one beta chain or one delta and one gamma chain. The beta locus includes V (variable), J (joining), diversity (D), and C (constant) segments. The Vß5 TCR is a variant of the TCR ß chain. It belongs to Ig superfamily and is expressed by a subset of peripheral blood T cells and some T cell clones. TCR Vß5 has been reported to recognize some staphylococcus bacterial superantigens.

    Thank you for your patience. For ab9219, the originator has recommended the following. Since the antibody recognizes human cytokeratin 18 we recommend using the PBS-insoluble fraction (pellet) of human cell lines containing cytokeratin 18 (for example Hela or T24, which was used for immunization of the mice) as a positive control in WB. You may also want to refer to the following publications for additional information about this antibody: Ramaekers F et al. Use of monoclonal antibodies to keratin 7 in the differential diagnosis of adenocarcinomas. Am J Pathol 136:641-55 (1990). PubMed: 1690512 Schaafsma HE et al. Distribution of cytokeratin polypeptides in human transitional cell carcinomas, with special emphasis on changing expression patterns during tumor progression. Am J Pathol 136:329-43 (1990).

    Thank you for your enquiry. The originator of ab1898 was able to provide me with the following information. Western blot detection: -material: HPB-ALL cell line -non-reducing conditions -detects only free beta chains -molecular weight 36 kDa The following publication has used this antibody and you may find some additional here as well: Pavlistová D et al. A novel monoclonal reagent recognizing native and denatured Vbeta5.3-related chains of human T cell receptor. Immunol Lett 88:105-8 (2003). PubMed: 12880678 I have not yet received information regarding ab9219 and will contact you again when I do.
