Non-radioactive in situ hybridization for the detection of cytomegalovirus infections.
Acetylaminofluorene (AAF) modified cytomegalovirus (CMV) DNA probes have been applied for the rapid detection of CMV genomes by non-radioactive in situ hybridization in routinely obtained pathological material. To establish proper protocols, AAF modified mouse satellite DNA and mouse liver were used to investigate the procedural variables. Among these were type and time of fixation, glass slide coating for improved tissue adherence, protease permeabilization of sections, type and time of denaturation and hybridization, probe concentration, post-hybridization washing conditions and immunocytochemical detection. This research has led to a user-friendly procedure which, in addition to cells displaying a cytopathological effect typical for CMV infection, detects with high sensitivity CMV carrying cells that show no histo-pathological alterations. It can be readily applied in routine clinical-diagnostic laboratories.
