IgG by IHC
12376 - Technical only, 12379 - Technical & interpretation
Immunoglobulin G
  • IgG labels plasma cells
  • IgG 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)
  • IgG will label occasional B cell lymphomas

Submit a formalin-fixed, paraffin-embedded tissue


Formalin-fixed, paraffin-embedded (FFPE) tissue block


FFPE tissue section mounted on a charged, unstained slide


Ambient (preferred)

  • Unlabeled/mislabeled block
  • Insufficient tissue
  • Slides broken beyond repair
AHL - Immunohistochemistry
Mo - Fr
1 - 2 days

Immunohistochemical staining and microscopic examination


If requested, an interpretive report will be provided



  • This antibody reacts with heavy chains (gamma) of human IgG (Fc-part)
  • This antibody labels plasma cells and various lymphocytes

 Staining pattern:

  • Cytoplasmic (plasma cells) and cell surface membrane (lymphocytes)
