  • Patent number: 7524821
    Abstract: Disclosed are scaffolded maleimide clusters, methods of making said clusters and use of said clusters as templates for multivalent peptide assembly. Multiple maleimide functionalities were introduced onto a scaffold molecule by the reaction of a core-centered polyamines with methoxycarbonylmaleimide or with activated esters of maleimide-containing compounds. The scaffolded maleimides allow rapid, highly chemoselective, and high-yield ligation with thiolcontaining peptides under virtually neutral conditions at room temperature. The disclosed mild and highly efficient ligation method is extremely valuable for synthesizing large and complex multivalent peptides that may not be easily obtained by conventional ligation methods. These novel scaffolded maleimide clusters allow a highly chemoselective ligation with a thiolcontaining peptide under virtually neutral conditions, providing a new and efficient approach for multivalent peptide assembly.

  • Publication number: 20090004461
    Abstract: The present invention relates to methods for functionally modifying a polymeric surface for subsequent deposition of metallic particles and/or films, wherein the polymeric surface is modified by increasing hydroxyl and/or amine functional groups thereby providing an activated polymeric surface for deposition of metallic particles to form a fluorescence sensing device. The device can be used for metal-enhanced fluorescence of fluorophores positioned above the metallic particles that can be readily applied to diagnostic or sensing applications of metal-enhanced fluorescence.

  • Patent number: 7462284
    Abstract: The present invention relates to a novel approach for nitrate removal from a marine recirculating system (10) wherein high concentrations of sulfate found in seawater is used in combination with sludge (20) collected from fish growing tanks (12) to promote dissimilatory sulfate reduction to hydrogen sulfide. The sulfide is used as an electron source to promote autotrophic denitrification in an up-flow fix bed bioreactor (16), followed by nitrification in a nitrification unit (14). By utilizing the symbiotic relationship between the sulfate-reducing and sulfide-oxidizing bacterial community, nitrate accumulation is controlled in the recirculating water of the system thereby reducing water exchange in the marine recirculating system.

  • Patent number: 7462480
    Abstract: Disclosed is a method for the anaerobic microbial dechlorination of polychlorinated biphenyls (PCBs). Polyhalogenated ethenes are used to stimulate the growth and dechlorinating activity of PCB dechlorinating bacteria in a contaminated soil or sediment. This method may be further coupled with aerobic microbial degradation of PCBs for the complete destruction of PCBs in soils and sediments. Polyhalogenated ethenes are also used in growth media for the culturing of PCB dechlorinating bacteria.

  • Patent number: 7399473
    Abstract: The invention relates to chimeric molecules comprising a virus coat sequence and a receptor sequence that can inter-act with each other to form a complex that is capable of binding a co-receptor. Such chimeric molecules therefore exhibit functional properties characteristic of a receptor-coat protein complex and are useful as agents that inhibit virus infection of cells due to occupancy of a co-receptor present on the cell. In particular aspects, the chimeric polypeptide includes an immunodeficiency virus envelope polypeptide, such as that of HIV, SIV, FIV, FeLV, FPV and herpes virus. Receptor sequences suitable for use in a chimeric polypeptide include, for example, CD4 D1D2 and CD4M9 sequences.

  • Patent number: 7247432
    Abstract: Small heat shock proteins, e.g., Pyrococcus fuiosus (Pfu-sHSP and/or Pfu-tsHSP), confer thermotolerance on cellular cultures and on proteins in cellular extracts during prolonged incubation at elevated temperature, demonstrating the ability to protect cellular proteins and maintain cellular viability under heat stress conditions. Such heat shock proteins are effective to combat enzymatic aggregation and intracellular precipitation during heat stress, and thereby enable enhancement of the utility and stability of enzymes in various applications, e.g., Taq polymerase in PCR applications, digestive enzymes in microbial degradative applications, etc.
