Title

ANTIGEN RETRIEVAL IMMUNOHISTOCHEMISTRY UNDER THE INFLUENCE OF PH

Pages

  207-211

Abstract

 Background: ANTIGEN RETRIEVAL (AR) incorporate high temperature heating of tissue sections before immunostaining that strongly increases intensity of IMMUNOHISTOCHEMICAL STAINING.Materials and methods: We have tested the hypothesis that PH of the AR solution may influence the quality of immunostaining by using 3 different AR buffer solutions at 3 different PH values (2.7, 6.16 and 9.27). We have evaluated the staining of 9 antibodies on routinely formalin fixed embedded sections under different PH condition with microwave heating for 10 minutes. The intensity of immounostaining was graded by two pathologists.Results: Antigens have revealed different patterns of staining in different PH. Some antigens showed more or less equal intensity of IMMUNOHISTOCHEMICAL STAINING in these PH. Others showed a dramatic decrease in the intensity of AR IMMUNOHISTOCHEMICAL STAINING at PH=6.16. Still others showed their strongest intensity in PH=9.27.Conclusion: According to several studies concerning optimization of AR system and the aforementioned findings, standardization of AR system should therefore include optimization of the temperature and PH. Meanwhile, PH=9.27 seems to be suitable for most antigens to be effectively retrieved.
