Abstract

An assay for the influenza virus endonuclease has been developed which involves DNA polymerase-catalyzed extension of the viral endonuclease cleavage product using labeled nucleotides and a DNA template containing a 3' region complementary to the product joined to a 5' region consisting of repeated residues. The DNA polymerase coupled assay does not involve gel electrophoretic separation and is amenable to high volume screening of potential inhibitors. Another key feature of the assay is that it is sensitive enough to detect 200 attomoles of product.
