      PE Mouse Anti-Human TCR Vβ23
      Two-color flow cytometric analysis of TCR Vβ23 expression on human peripheral blood T lymphocytes. Human peripheral blood cells were stained with APC Mouse Anti-Human CD3 antibody (Cat. No. 561811) and with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Left Plot) or PE Mouse Anti-Human TCR Vβ23 antibody (Cat. No. 568573/568574; Right Plot). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). The bivariate pseudocolor density plot showing the correlated expression of TCR Vβ23 (or Ig Isotype control staining) versus CD3 was derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

      Preparation And Storage

      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 and unconjugated antibody and free dye were removed.

      Recommended Assay Procedures

      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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

      Product Notices

      1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      3. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
      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.
      6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      7. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).

      AHUT7

      The AHUT7 monoclonal antibody specifically recognizes the human variable beta 23 region of the β subunit of the human αβ T cell receptor for antigen (TCR Vβ23). The  TCR Vβ23 region is encoded by the TRBV13 gene segment. TCR Vβ23 is expressed on subsets of TCR αβ positive thymocytes and on ~0.3 to 5% of peripheral blood T cells including CD4+ and CD8+ T cells. The AHUT7 antibody is useful for multiparameter analyses designed to study the nature of TCR Vβ23-positive T cells including normal T cells as well as T cell clones, hybridomas, or tumor cell lines including H9 and HUT-78. It is also useful for analyzing TCR Vβ repertoires expressed by T cell populations collected from blood, tissues or other sources in health and disease models including inflammation, autoimmunity, responses to superantigens, tumors, and infectious diseases. The AHUT7 antibody can reportedly stimulate the proliferation of TCR Vβ23-positive T cells.

      PE
      R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
