title: Application of the hybridization AT-tailing method for detection of human immunodeficiency virus RNA in cells and simian immunodeficiency virus RNA in formalin-fixed and paraffin-embedded tissues.
abstract: An in situ hybridization (ISH) AT-tailing method (HybrAT) was developed for the detection of viral genomes in infected cells and tissues. The method consists of hybridization with oligonucleotide probe which has a 3' end oligo d(A-T) tag, followed by elongation of the oligo d(A-T) by deltaTth DNA polymerase in the presence of the labeled nucleotide. The in situ HybrAT detected human immunodeficiency virus type 1 (HIV-1) in cells and simian immunodeficiency virus (SIV) in formalin-fixed and paraffin embedded sections with a sensitivity comparable to RNA ISH. The advantage of this method over other methods is discussed.
