Hematoxylin-lac-curcuma polychrome stain for mucin.
Artigo em Inglês | IMSEAR | ID: sea-45110
ABSTRACT
A polychrome method for detection of mucin substance in paraffin section is produced by sequential stepwise staining of hematoxylin, crude lac extract (Laccifer lacca), and crude curcuma extract (khamin shan-Curcuma longa). The name LacCur stain is proposed. After a tissue section is deparaffinized and rehydrated, it is stained with Weigert's hematoxylin for 7 minutes. After a quick wash, it is stained for at least 3 hours with lac dye mordanted with aluminum chloride. Washed again and premordanted with ferric chloride for 1 minute, in the last step, it is counterstained with curcuma dye for 5 minutes. With this staining method, the nuclei are stained black, mucin deep red, and organelles and ground substances brownish yellow. The method and outcome colors are comparable to the widely used Mayer's mucicarmine staining method. It costs less than the Mayer's mucicarmine staining method and the procedure is not complicated.
