Patent number: 6821742Abstract: Methods and compositions are provided for identifying novel conformers of proteins not known to exist as different conformers. By using chimeric genes replacing a native signal sequence with a different signal sequence resulting in the production of a conformer, one can compare the native protein with the product of the chimeric gene. Where the conformations are different, the different protein may be used for production of antibodies, elucidation of mechanisms associated with the native and different conformer protein, assays for the presence of the different conformer in physiological samples, identification of compounds specifically binding to the conformer, particularly drugs, etc. Where the formation of the conformer is associated with a diseased state, the conformer may be used in screens to identify compounds as drug candidates.Type: GrantFiled: December 15, 2000Date of Patent: November 23, 2004Assignee: Regents of the University of CaliforniaInventors: Vishwanath R. Lingappa, D. Thomas Rutkowski, Ramanujan S. Hegde

Patent number: 6592769Abstract: A device is provided for the filter and collection of one or more material. The device incorporates a manifold with an inlet conduit and an outlet conduit, with an adjustable control handle on the top of the manifold and a baffle plate in the inside of the manifold. The manifold is sealed to the top opening of a collection chamber. During procedures which require withdrawal of material not to be collected, the control handle and baffle plate are adjusted to a pass-through mode which connects a internal adjustable conduit, which transverses through the baffle plate, with the lumen of the inlet and outlet conduits to form a continuous lumen with which to withdraw material not to be collected through. During procedures which require the withdrawal of material to be collected, the control handle and baffle plate are adjusted to a solids mode which orients the baffle plate to face both the lumen of the inlet and outlet conduits.Type: GrantFiled: August 17, 2000Date of Patent: July 15, 2003Inventor: Roger T.
