Abstract
Analysis of surgical pathology specimens by histological techniques including immunohistochemistry (IHC) assays is a mainstay of disease diagnosis in humans. Neutral buffered formalin (NBF) is currently the primary fixative used, but its use is not without risks due to toxicity and carcinogenicity. Several glyoxal-based fixatives have been commercially produced, are considered safer alternatives to NBF, and produce histochemical staining results comparable to that of tissues fixed in NBF. However, previous studies evaluating IHC assay results in tissues fixed in NBF and glyoxal solutions have indicated mixed results. This study demonstrated that while tissues fixed in NBF were slightly superior to tissues fixed in glyoxal solutions among the 34 antibodies assayed with IHC, all fixative solutions produced results compatible for use in an anatomic pathology laboratory.
期刊介绍：
The official journal of the National Society for Histotechnology, Journal of Histotechnology, aims to advance the understanding of complex biological systems and improve patient care by applying histotechniques to diagnose, prevent and treat diseases.
Journal of Histotechnology is concerned with educating practitioners and researchers from diverse disciplines about the methods used to prepare tissues and cell types, from all species, for microscopic examination. This is especially relevant to Histotechnicians.
Journal of Histotechnology welcomes research addressing new, improved, or traditional techniques for tissue and cell preparation. This includes review articles, original articles, technical notes, case studies, advances in technology, and letters to editors.
Topics may include, but are not limited to, discussion of clinical, veterinary, and research histopathology.
