Patent number: 7129036Abstract: The invention relates to reporter molecules comprising at least one detection domain capable of emitting a signal and at least one membrane anchoring domain, which promotes the association of the reporter molecule with a membrane. The degree and rate of membrane association of the reporter molecule is approximated by the signal emitted by the detection domain. This signal provides a marker for the membrane association status of the membrane anchoring portion, or of the reporter molecule as a whole. Treatments or agents may be tested for their ability to alter membrane association or localization by observing or measuring the signal emitted by the detection domain. Thus, the invention provides means and methods for determining the capability of an agent to interfere at least in part with the distribution of a reporter molecule in a cell. These methods are useful for drug discovery; the phenotypic evaluation of cells, preferably patient cells; and for tailoring a therapeutic program for treating a patient.Type: GrantFiled: May 26, 2000Date of Patent: October 31, 2006Assignee: Tibotec BVBAInventors: Koenraad Lodewijk August Van Acker, Inge Dierynck, Rudi Wilfried Jan Pauwels

Patent number: 7087375Abstract: 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.Type: GrantFiled: June 23, 2000Date of Patent: August 8, 2006Inventors: Johan Lennerstrand, Brendan Larder
