2004 AUG 4 - (NewsRx.com & NewsRx.net) -- Researchers have developed a DNA microarray format for detection and subtyping of human papillomavirus.
"A new human papillomavirus (HPV) assay using high-density DNA microarrays; is described. An HPV DNA fragment from the 3' end of the E1 gene was amplified and digoxigenin labeled by PCR, and the resulting amplicons were hybridized onto type-specific oligonucleotides immobilized on high-density DNA microarrays. For detection, a simple immunohistochemical staining procedure was used with a substrate that has both colorimetric and fluorescent properties," researchers in the Netherlands report.
"This detection chemistry enables the rapid identification of reactive spots by regular light microscopy and semiquantification by laser scanning," stated Corne H. W. Klaassen and colleagues at Canisius Wilhelmina Hospital. "Both single and multiple HPV infections are recognized by this assay, and the corresponding HPV types are easily identified. With this assay, 53 mucosal HPV types were detected and identified. A total of 45 HPV types were identified by a single type-specific probe, whereas the remaining 8 mucosal HPV types could be ...
