As part of an ongoing tradition in which textile dyes are used for biological staining, several new stains have been applied to hematologic staining.

BrdU was administered intravenously 2 hr before death and uterine blocks were embedded in polyester wax and Technovit resin after fixation in formalin and periodate-lysine-paraformaldehyde, respectively. The indirect method with anti-BrdU and fluorescein isothiocyanate (FITC) conjugated antimouse IgG antisera and the direct method with FITC conjugated anti-BrdU antibody were applied to both wax- and resin-embedded sections. Labeled and total cells were counted in luminal and glandular epithelia and stomata adjoining them. Counterstaining with hematoxylin for counting total cells produced intense fluorescence over the whole of resin sections and made counting of labeled cells impossible. On wax sections, on the other hand, the results were satisfactory, although the number of labeled cells detected was decreased slightly. In wax sections fluorescence due to nuclear incorporation of BrdU in the indirect method could be easily distinguished from the cytoplasmic or extracellular emission seen in some cells by its location and characteristic color. In resin sections, however, more careful observation was needed since the second antibody used in the indirect method cross-reacted with IgG in eosinophils and produced cytoplasmic fluorescence of the same color. By the indirect method greater numbers of labeled cells were detected in wax sections than in resin sections. The difference was distinct in tissues with extensive cell proliferation. By the direct method the fluorescence obtained was weaker and apt to fade more quickly than that obtained by the indirect method; use of the direct method reduced the number of labeled cells detected in both wax- and resin-embedded sections.</p>","PeriodicalId":21924,"journal":{"name":"Stain technology","volume":"65 3","pages":"139-49"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/10520299009139927","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12860106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
