  • Publication number: 20060246427
    Abstract: The present invention is directed to the field of HIV resistance to RT inhibitors and methods of determining the levels and mechanisms of action of HIV resistance. The methods of the present invention may be accomplished using a novel in vitro assay that provides a reaction well comprising a template for an HIV RT enzyme, a primer, a detectable dNTP substrate, an HIV RT inhibitor, and a ribonucleotide chosen from ATP and GTP or a pyrophosphate. The RT activity is determined by measuring the amount of the detectable dNTP substrate that is incorporated into the template, and the level and/or mechanism of resistance of HIV to the HIV RT inhibitor is determined using the RT activity. The methods may also be used for designing new therapies, screening for new drugs and treatments, and determining the role of mutations in observed resistance.

  • Patent number: 6132995
    Abstract: A method for determining the activity of a nucleotide polymerizing enzyme in a sample, and use of the method for determining HIV 1 RT- and Herpes Simplex DNA-polymerase activity. The enzyme is captured by means of a nonoclonal antibody which is immobilized to a solid carrier and is capable of binding the enzyme without detrimentally effecting the enzyme activity. Contaminants and disturbing factors are removed and the nucleotide polymerization starts by the addition of a reaction solution containing a primer/template construct and nucleotides substrate, the reaction conditions being chosen such that they promote permanent association between antibody enzyme- and primer/template constructs. When necessary a nucleotide substrate, primer/template and reaction solution are washed away from the newly synthesized polymer, and the amount of nucleotide which as been incorporated into the polymer is determined, and the activity of the enzyme is determined with the guidance of this determination.
