  • Patent number: 7807400
    Abstract: The present invention provides a method of identifying a compound having the ability to modulate the guanine nucleotide exchange cycle of a Ras superfamily GTPase, comprising: a) contacting the compound with a guanine nucleotide exchange factor and a GTPase and obtaining a baseline fluorescence measurement; b) contacting the guanine nucleotide exchange factor and the GTPase without the compound and obtaining a baseline fluorescence measurement; c) adding a fluorophore-conjugated GTP to the components of (a) and (b), respectively; d) obtaining fluorescence measurements of the respective components of (c) over time; e) subtracting the respective baseline fluorescence measurements of (a) and (b) from each fluorescence measurement of (d); and f) comparing the resulting fluorescence values of (e), wherein a decrease or increase in the rate of fluorescence change with the compound as compared with the rate of fluorescence change without the compound identifies a compound having the ability to modulate the guanine n

  • Patent number: 6196902
    Abstract: An apparatus for finishing the edge of a sheet of glass, which includes a supporting structure with a support base, a stationary vertical structure coupled on the support base, and, an upper supporting arm located in a horizontal position on the vertical stationary structure. A motor is connected at one end of the upper supporting arm. Grinding means are connected to the motor fort finishing or grinding the edge of sheet of glass. A housing for housing the grinding means, which includes a fixed upper section and a removable lower section. A longitudinal groove is made in the housing for the introduction of the edge of the glass sheet to contact with the grinding means in order to finish the edge of the glass sheet. Cooling means are located within the housing for cooling the periphery, lower and upper sections of the grinding means during the finishing of the edge of the glass sheet.
