Formalin-fixed and paraffin-embedded human prostate carcinoma tissue reacted with STAP1 polyclonal antibody (Cat # PAB1880) , which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
