    FITC Mouse Anti-Human NKB1
    FITC Mouse Anti-Human NKB1
    Flow cytometric analysis of NKB1 (CD158e1) expression on human peripheral blood lymphocytes. Whole blood was stained with FITC Mouse Anti-Human NKB1 (CD158e1) (Cat. No. 555966) and PE Mouse Anti-Human CD56 (Cat. No.555516/561903). Erythrocytes were lysed with BD FACS Lysing Solution (Cat. No. 555899).The fluorescence dot plot was derived from gated events with the forward and side light-scattering characteristics of viable lymphocytes.

    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 FITC under optimum conditions, and unreacted FITC was 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. 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.
    4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
    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 http://regdocs.bd.com to access safety data sheets (SDS).
    7. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

    DX9

    The DX9 monoclonal antibody specifically binds to CD158e1, also known as NKB1. CD158e1 functions as a killer cell inhibitory receptor (KIR) and is encoded by KIR3DL1 (Killer cell immunoglobulin-like receptor, three domains, long cytoplasmic tail).  CD158e1 is a 70 kDa glycoprotein that belongs to the Ig superfamily. It is expressed on a subset of natural killer cells and a small subset of T cells. Expression of CD158e1 has been observed to vary among individuals. KIR molecules specifically recognize a certain group of HLA class I antigens. Interaction of CD158e1 with specific HLA-B antigen on a target cell appears to inhibit cell-mediated cytotoxicity by delivering a negative signal that prevents lymphocyte activation. It is suggested that this MHC class I-KIR interaction works as a signaling mechanism that regulates NK and T-cell responses to antigenic challenge.

    FITC
    Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
