    PE Mouse Anti-Human TCR Vα7.2
    PE Mouse Anti-Human TCR Vα7.2
    Two-color flow cytometric analysis of TCR Vα7.2 expression on human peripheral blood cells. Human whole blood was stained with BD Horizon™ BV421 Mouse Anti-Human CD3 antibody (Cat. No. 562426/562427) and either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Left Plot) or PE Mouse Anti-Human TCR Vα7.2 antibody (Cat. No. 566739; Right Plot). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Pseudocolor density plots showing the correlated expression of CD3 versus TCR Vα7.2 (or Ig Isotype control staining) were 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™ 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 with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

    Product Notices

    1. 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).
    2. An isotype control should be used at the same concentration as the antibody of interest.
    3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
    4. 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.
    5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
    6. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

    OF-5A12

    The OF-5A12 monoclonal antibody specifically recognizes the human variable alpha 7.2 region of the T cell receptor for antigen (TCR Vα7.2) that is joined with the Jα33 segment to form an invariant TCR which is characteristically expressed by mucosal-associated invariant T cells (MAIT cells). MAIT cell recognition of antigen is restricted by MHC-related molecule 1 (MR1), a nonpolymorphic Class Ib Major Histocompatibility Complex (MHC) molecule, that associates with β2-microglobulin. MAIT cells are found in human peripheral blood, mesenteric lymph nodes, liver, and mucosa associated with the lungs and intestines. MAIT cells play a role in detecting and fighting off microbial infections. The specificity of OF-5A12 for the TCR Vα7.2 was confirmed by its ability to block the binding of another human TCR Vα7.2-specific antibody, 3C10, to MAIT 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.
