Anti-Natural Killer Cell antibody [ANK44] (ab36388)


  • Product nameAnti-Natural Killer Cell antibody [ANK44]
  • Description
    Mouse monoclonal [ANK44] to Natural Killer Cell
  • Specificityab36388 also binds to rat gamma-delta-TCR T cells. It does not bind to alpha-beta-TCR T cells or to B cells. The antigen recognized by ab36388 is highly expressed on rat NK cells after IL-2-activation. The antigen is not expressed by unstimulated NK cells.

  • RelevanceNatural killer cells (NK) are a type of lymphocyte and a component of innate immune defense. They share a common progenitor with T cells and have been described as large, granular, bone-marrow derived lymphocytes. These cells do not destroy the attacking microorganisms directly; they attack infected cells and cells that appear that they might be cancer. NK cells are not phagocytic; they weaken the target cell's plasma membrane, causing water and ions to diffuse into the cell and expanding it. Under this large pressure, the target cell lyses. NK cells are characterised immunohistochemically by the presence of CD56 and the absence of CD3 on the cell membrane. NK cells are activated in response to interferons or macrophage-derived cytokines. They serve to contain virus infections while the adaptive immune response is generating antigen specific cytotoxic T cells that can clear the infection. Patients deficient in NK cells prove to be highly susceptible to early phases of herpes virus infection.
