[Hybridization using a digoxigenin-labeled probe for the detection of hepatitis delta virus].
1992
BACKGROUND: The presence of hepatitis delta virus was investigated in liver biopsies by in situ cyto-hybridization with a probe labelled with digoxigenin. METHODS: The techniques developed included extraction of plasmid DNA by lysis by alkali, electroelution, electrophoresis in agarose gel and digoxigenin labelling, and the application in liver tissue. RESULTS: Viral RNA was detected in 6 of the 10 patients, and the reactivity was exclusively restricted to the nucleolus of the hepatocytes. CONCLUSION: This method reveals as a sensitive and quick diagnostic procedure, which allows to study the intensity of the infection as well as the serological state of the patient.
