  • Patent number: 6428951
    Abstract: We describe a strategy for designing and implementing protein-fragment complementation assays (PCAs) to detect biomolecular interactions in vivo and in vitro. The design, implementation and broad applications of this strategy are illustrated with a large number of enzymes with particular detail provided for the example of murine dihydrofolate reductase (DHFR). Fusion peptides consisting of N- and C-terminal fragments of murine DHFR fused to-GCN4 leucine zipper sequences were coexpressed in Escherichia coli grown in minimal medium, where the endogenous DHFR activity was inhibited with trimethoprim. Coexpression of the complementary fusion products restored colony formation. Survival only occurred when both DHFR fragments were present and contained leucine-zipper forming sequences, demonstrating that reconstitution of enzyme activity requires assistance of leucine zipper formation. DHFR fragment-interface point mutants of increasing severity (lie to Val, Ala and Gly) resulted in a sequential increase in E.

  • Patent number: 6387137
    Abstract: Liquid hydrocarbons are gelled by the introduction of a phosphate ester and a crosslinking agent. Gelling times and viscosities are improved through the use of an enhancer which is, preferably, an oxyalkylated amine or a blend of an oxyalkylated amine with another amine or a non-nitrogen-containing component. Preferred phosphate esters are ether phosphate esters.

  • Patent number: 6342468
    Abstract: The invention relates to compositions and methods for gelling liquid hydrocarbons by the introduction of certain phosphate esters, a crosslinking agent, and an enhancer. The enhancer of the present invention is preferably an oxyalkylated amine or a blend of an oxyalkylated amine with another amine or a non-nitrogen-containing component. Mixed phosphate esters containing an oxyalkylene group are useful in the practice of the invention. Gel-forming compositions for addition to liquid hydrocarbons, as well as methods for forming fracturing fluids, are encompassed.

  • Patent number: 6294330
    Abstract: The invention provides a general protein-fragment complementation assays to detect biomolecular interactions in vivo and in vitro. The protein-complemetation assay/universal reporter system can be used to detect and screen an agonist and an antagonist of a membrane receptor system. The assay can be used to study protein-protein, protein-DNA, protein-RNA, protein-carbohydrate, and protein-small molecule interactions. The assay can be used to screen cDNA libraries for binding of a target protein with unknown proteins or libraries of small organic molecules for biological activity.

  • Patent number: 6286253
    Abstract: A method for planting and stabilizing soilless sods is taught, beginning with planting pure stock of the desired cultivar in sterile media over plastic sheeting. The pure stock, once it has matured into a sod, it is harvested and milled into vegetative planting material. The milled material is suspended in a liquid slurry in an agitating tank and discharged into a trailing planter assembly that spreads the slurry evenly over unrolling plastic sheeting where it acts not only as planting material but, in sufficient quantities, also as a stabilizing protective mulch that maintains the integrity of the young sod crop in severe storms. Unlike sprigs or stolons the milled planting stock is produced from whole plant tissue and is comprised of many plantlets with intact root, stem, and leaf tissue. A bushel of milled turf plantlets is much more dense than a bushel of sprigs or stolons and comprises meristems from all parts of the plant including roots, crowns, and rhizomes.
