The Histopathology Shared Resource (HSR) provides Immuhistochemistry services which include:

  • Testing and titering new antibodies, both monoclonal and polyclonal. The latter should be either a purified IgG fraction or affinity-purified. (Straight serum is not suitable for immunostaining).
  • Optimization of staining to enhance detection and reduce background.
  • Epitope retrieval techniques (pre-treatment with heat and/or proteases)
  • Specialized secondary detection reagents
  • Avidin/biotin blocking steps
  • Double- and triple-antibody stains using multiple chromagens.

Immunohistochemistry (IHC) services provided by the Histopathology Shared Resource (HSR) can be performed using the Ventana Benchmark XT platform (automated) or stained by hand (manual).
