Application Abreviews Notes
IHC-P 1/25 - 1/50. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. For an ABC system, incubate for 30-60 minutes at RT.
IHC-Fr 1/25 - 1/50. For an ABC system, incubate for 30-60 minutes at RT.


  • FunctionAntigen-presenting protein that binds self and non-self lipid and glycolipid antigens and presents them to T-cell receptors on natural killer T-cells.
  • Tissue specificityExpressed on cortical thymocytes, epidermal Langerhans cells, dendritic cells, on certain T-cell leukemias, and in various other tissues.
  • Sequence similaritiesContains 1 Ig-like (immunoglobulin-like) domain.
  • Cellular localizationCell membrane. Endosome membrane. Subject to intracellular trafficking between the cell membrane and endosomes. Localizes to cell surface lipid rafts.
