Abstract:
It has been known that eosinophilia in the peripheral blood or tissue participate in allergic inflammatory reactions and parasitic diseases. The function of eosinophils depend on the biological activity of the granule proteins. Four of these protein-MBP, ECP, EPO, and EDN have been known. There are some assumptions that the eosinophils might cause a tissue damage on examination of their specific protein. Therefore, the measurements of these granule proteins might clarify the pathogenesis of eosinophils related diseases. In this review, we introduce a convenient method for purification, quantitative measurement in serum, BAL and detection of localization in tissue by an immunofluorescence method for specific staining of eosinophil granule proteins.
