  • Patent number: 6500623
    Abstract: A replication-defective HIV particle pseudotyped with vesicular stomatitis virus G protein (VSV-G). The pol gene of the HIV genome in the particle is modified to inactivate the pol reverse transcriptase and protcase activity. This pseudotyped HIV particle can infect many cell types, including human and simian cells, and only undergoes one round of replication. Furthermore, a virus-specific immune response can be detected in mice immunized with the VSV-G pseudotyped replication-defective HIV.

  • Patent number: 6492128
    Abstract: A drug screening assay for identifying compounds for their potential effects on the long chain fatty acid dependant intracellular membrane anchorage sites of lipoproteins. Membranes-anchoring-target are incubated in the presence of the compound to be tested and the proportion of the target that is released by the compound is detected and quantitated. The benchmark for this assay are the prenylated proteins such as the farnesylated and palmitoylated oncogenic ras trigger proteins which are displaced from their anchorage at the intracellular plasma membrane by derivatives of Farnesyl Thiosalicylic Acid (FTS). The assay is adaptable to flexibly assay a large variety of anchored targets using a wide range of labeling and detection techniques in test wells, tissue culture, and in animals as injected cells or transgenic, thereby directly addressing a wide range of pharmacologically relevant needs.
