Abstract
Many attempts have been made to simplify tissue fixation and processing prior to hematoxylin and eosin (H&E) staining, immunohistochemistry (IHC) and genomic DNA extraction. The acetone-methyl benzoate-xylene (AMeX) method, is gaining popularity as an alternative to aqueous formaldehyde fixation followed by alcohol dehydration. We have assessed the efficacy of AMeX for the quality of extracted genomic DNA in addition to H&E and IHC in biopsy specimens of human oral mucosal lesions of size not more than 1 cm. H&E staining showed similar results when AMeX method was compared with conventional fixation and processing. Improved IHC staining quality was observed in the sections of AMeX-processed tissue, as were improved quality and quantity of genomic DNA.
期刊介绍:
Biotechnic & Histochemistry (formerly Stain technology) is the
official publication of the Biological Stain Commission. The journal has been in continuous publication since 1926.
Biotechnic & Histochemistry is an interdisciplinary journal that embraces all aspects of techniques for visualizing biological processes and entities in cells, tissues and organisms; papers that describe experimental work that employs such investigative methods are appropriate for publication as well.
Papers concerning topics as diverse as applications of histochemistry, immunohistochemistry, in situ hybridization, cytochemical probes, autoradiography, light and electron microscopy, tissue culture, in vivo and in vitro studies, image analysis, cytogenetics, automation or computerization of investigative procedures and other investigative approaches are appropriate for publication regardless of their length. Letters to the Editor and review articles concerning topics of special and current interest also are welcome.
