Immunological and Immunohistochemical Studies in Brain Tumours

The authors have studied different brain tumours with immunohistochemical technique using fluorescence and peroxidase methods. On frozen sections reactions for fibronectin (FN), prostaglandin E 2 (PGE 2), carcinoembryonic antigen (CEA) with polyclonal antibodies and for lymphocyte subpopulations B, NK and Pan-T with monoclonal antibodies have been investigated.
