Immunoglobulin A
  
  • All IHC stains will include a positive control tissue
  
  • IgA labels plasma cells and related lymphoid cells containing IgA
  • IgA stains will show an interstitial dendritic pattern within lymphoid follicles, (this represents extracellular immune complexes which are bound to the surface of specialized follicular dendritic cells)
  • IgA will label occasional B cell lymphomas
