  • Publication number: 20060183157
    Abstract: A method for characterizing interactions in macromolecular complexes, such as protein-protein or protein-ligand complexes, by selective isotopic labeling of the target molecule to reduce the 1H density in a selected spectral region; by irradiating the target; and by monitoring the polarization using filtered nuclear Overhauser spectroscopy (NOESY) and/or by performing selective saturation transfer experiments to determine the docking potential of the macromolecular complex.

  • Patent number: 6642059
    Abstract: The present invention is a method for accurately comparing the levels of cellular components, such as proteins, present in samples which differ in some respect from each other using mass spectroscopy and isotopic labeling. A first sample of biological matter, such as cells, is cultured in a first medium and a second sample of the same biological matter is cultured in a second medium, wherein at least one isotope in the second medium has a different abundance than the abundance of the same isotope in the first medium. One of the samples is modulated, such as by treatment with a bacteria, a virus, a drug, hormone, a chemical or an environmental stimulus. The samples are combined and at least one protein is removed. The removed protein is subjected to mass spectroscopy to develop a mass spectrum. A ratio is computed between the peak intensities of at least one closely spaced pair of peaks to determine the relative abundance of the protein in each sample.

  • Patent number: 5888763
    Abstract: The present invention relates to regulation and control of cellular processes by SH3-domain binding proteins and peptides. In particular, the invention provides a consensus sequence of a peptide that shows high specificity and affinity for the first SH3 domain of cellular Crk. In specific examples, a number of peptides that contain the consensus are shown to bind c-Crk specifically. The molecular basis for this specificity is examined by crystallography.

  • Patent number: 4887841
    Abstract: A suspension for a pair of wheels of a motor vehicle, comprising a spring (10,30) extending tranversely of the vehicle and supported by two mountings (11,12) spaced between the spring ends and which ends are connected, directly or indirectly, to wheel carrier members, wherein the spring has a portion (22,24) displaced out of the general line of adjacent parts of the spring to give a clearance from a part of the vehicle. The displaced part of the spring may be the entire central portion (40,50,60,100) thereof between its mountings (45,46,101) and end portions of the spring may be inclined to such central portion, so that the space directly between the wheels is clear of suspension parts.
