Reactivity

Clone TC8 has been developed specifically for the immunohistochemical (IHC) detection of CD8 in routine FFPE human tissue specimen. TC8 has been validated for the identification of CD8 positive tumor infiltrating T cells (TILs) with the aim to allow an unequaled specific detection of CD8 in the tumor microenvironment. IHC application of monoclonal antibody TC8 may provide valuable information for clinical research and potential therapeutic interventions targeting the tumor immunology checkpoint.
