Application of the NASBA nucleic acid amplification method for the detection of human papillomavirus type 16 E6-E7 transcripts.

ABSTRACT

Using a human papillomavirus type 16 (HPV-16) E6-E7 specific primer set in a nucleic acid sequence-based amplification (NASBA) reaction, detection of HPV-16 transcripts was accomplished in a single enzymatic reaction at 41 degrees C. The NASBA reaction product was visualized either by Northern bolt analysis with an HPV-16 E6-E7-specific 32P-labelled oligonucleotide probe or by a non-radioactive enzyme-linked gel assay (ELGA). In combination with a rapid nucleic acid extraction procedure this method appears to be very suitable for the sensitive and specific detection of HPV-16 transcripts on small amounts of HPV-16-expressing cells of various sources, including cervical smears.
