Immunocytochemical methods for demonstrating canine distemper virus antigen in aldehyde-fixed paraffin-embedded tissue

Research output: Contribution to journalArticlepeer-review

Abstract

The effects of enzymatic digestion, sodium borohydride reduction, acids used in décalcification procedures and techniques for inactivation of endogenous peroxidase were sequentially evaluated for their effect on the immunoreactivity of canine distemper virus in aldehyde-fixed paraffin-embedded tissue. Enzyme digestion improved immunoreactivity while sodium borohydride reduced background staining. Paraformaldehyde-glutaraldehyde-fixed tissues required thioglycolic acid treatment prior to enzyme digestion and sodium borohydride reduction to obtain results comparable to results obtained in formalin-fixed tissues. Detailed protocols for indirect immunofluorescence and the avidin-biotin-peroxidase complex procedure are provided.
