  • Patent number: 8241627
    Abstract: The present invention provides a method for stabilizing a protein in a desired conformation by introducing at least one disulfide bond into the polypeptide. Computational design is used to identify positions where crysteine residues can be introduced to form a disulfide bond in only one protein conformation, and therefore lock the protein in a given conformation. Accordingly, antibody and small molecule therapeutics are selected that are specific for the desired protein conformation. The invention also provides modified integrin I-domain polypeptides that are stabilized in a desired conformation. The invention further provides screening assays and therapeutic methods utilizing the modified integrin I-domains of the invention.

  • Publication number: 20040171073
    Abstract: Methods for regulation of lipid and cholesterol uptake are described which are based on regulation of the expression or function of the SR-BI HDL receptor. The examples demonstrate that estrogen dramatically downregulates SR-BI under conditions of tremendous upregulation of the LDL-receptor. The examples also demonstrate the upregulation of SR-BI in rat adrenal membranes and other non-placental steroidogenic tissues from animals treated with estrogen, but not in other non-placental non-steroidogenic tissues, including lung, liver, and skin. Examples further demonstrate the uptake of fluorescently labeled HDL into the liver cells of animal, which does not occur when the animals are treated with estrogen. Examples also demonstrate the in vivo effects of SR-BI expression on HDL metabolism, in mice transiently overexpressing hepatic SR-BI following recombinant adenovirus infection. Overexpression of the SR-BI in the hepatic tissue caused a dramatic decrease in cholesterol blood levels.

  • Patent number: 6689267
    Abstract: An improved electrophoresis device includes first and second end reservoirs of buffer, and a separation tank between the end reservoirs. The separation tank fluidically interconnects the reservoirs and is configured to hold a stack of gel trays in an oriented electric field and covered by the buffer solution. At least one gas-driven fluid recirculation passage distinct from the separation tank drives buffer in one direction between the reservoirs, and stabilizes the buffer below the level of the trays, while stabilized buffer completes circulation between the stack of trays without thermal or chemical upset of the electrophoresis conditions over time. The device may have the same footprint as a conventional single-tray vessel, while having increased capacity for performing electrophoresis operations.
