D. Biernacka et al., MICROWAVE-ASSISTED STAINING OF MUCOSAL MAST-CELLS AND GRANULATED INTRAEPITHELIAL LYMPHOCYTES AFTER FORMALIN FIXATION, Histochemical Journal, 25(12), 1993, pp. 854-856
Rat jejunum was fixed with either formalin or methanol-formalin acetic
acid (MFAA) and stained with Astra Blue or Alcian Blue with or withou
t microwave irradiation. Staining of both mucosal mast cells and granu
lated intra-epitheliar lymphocytes after formalin fixation was conside
rably improved by microwave irradiation. On the other hand, microwave
irradiation slightly impaired staining of mucosal mast cells (MMC) and
even more strongly granulated intra-epithelial lymphocytes (GIEL) aft
er MFAA fixation.
