title: Demonstration of myoglobin in formalin-fixed renal sections by immunoperoxidase technic.
abstract: The use of an immunohistochemical technic offers a very sensitive method to detect myoglobin in formalin-fixed, paraffin-embedded tissues. Thus, the technic is suitable for retrospective studies. Myoglobin can be demonstrated at the brush border and apical cytoplasm of the tubular epithelium of proximal tubules. Granular substances and casts in the lumens also react positively with antimyoglobin. Our findings confirm the results of a previous animal study, showing that myoglobin is filtered through glomeruli and reabsorbed by the proximal tubules.
