Immunohistochemistry (IHC) · All
Spirochete (Treponema pallidum) is the causative agent of syphilis. In the past, localization of the spirochete agent was achieved with silver stains such as Steiner's and/or Warthin-Starry. Treponema pallidum can now be successfully localized with immunohistochemical techniques in formalin-fixed paraffinembedded tissue. Studies have shown this offers a substantial advantage over silver-techniques in both sensitivity and specificity. The antibody consists of a rabbit purified IgG fraction and is highly specific for spirochete (1).
