PMID:  2079108     Owner:  NLM     Status:  MEDLINE    
The simultaneous use of two immunoperoxidase (IP) methods; e.g. the PAP (Peroxidase-antiperoxidase) and ABC (Avidin-Biotin) to localize a single antigen enhances the sensitivity of polyclonal antibodies (FVIII/RAg and laminin) or monoclonal antibodies (MABs) (against human B-, T-cells and macrophages) in routinely formalin fixed and in paraffin embedded material. The increased sensitivity was not accompanied by loss of specificity. With antibodies against Factor VIII related antigen (FVIII/RAg) and laminin the increased staining intensity of blood vessels were demonstrated in experimental rat transplantation tumors. The similar enhancement of immunocytochemical reactions was observed with biopsies of human brain tumors, where the monoclonal antibodies against white blood cells were used. The staining results were of comparable intensity as in snapfrozen tissue or after special embedding procedure for immunocytochemical purposes acc. to Bolton and Mesnard formol sucrose gum, sucrose paraffin; FSGSP).
