Patent number: 6284453Abstract: This invention is a method for controlling growth rate and metabolic state in fed-batch fermentations. Growth rate refers to the rate of exponential growth. Metabolic state refers to the relative consumption rates of the carbon and nitrogen sources.

Patent number: 6280618Abstract: Heterogeneous assays for different analytes in a single biological sample are performed simultaneously in a multiplexed assay that combines flow cytometry with the use of magnetic particles as the solid phase and yields an individual result for each analyte. The particles are distinguishable from each other by characteristics that permit them to be differentiated into groups, each group carrying an assay reagent bonded to the particle surface that is distinct from the assay reagents of particles in other groups. The magnetic particles facilitate separation of the solid and liquid phases, permitting the assays to be performed by automated equipment. Assays are also disclosed for the simultaneous detection of antibodies of different classes and a common antigen specificity or of a common class and different antigen specificities.Type: GrantFiled: April 30, 1999Date of Patent: August 28, 2001Assignee: Bio-Rad Laboratories, Inc.Inventors: Michael I. Watkins, Richard B. Edwards

Patent number: 6267925Abstract: A system dynamically adjusts the delivery rate of a cryopreservation solution to red blood cells to permit freezing. The delivery rate is preferably determined according to an equation that maintains a linear change of red blood cell osmolarity over time so as to prevent osmolarity shock of the red blood cells. In the preferred embodiment, the system includes a controller that is preconfigured to automatically deliver the cryopreservation solution to the red blood cells in accordance with the equation. The system may also support the recovery of thawed red blood cells by diluting the red blood cells and washing them of the cryopreservative. Again, the system preferably adjusts the delivery rate of a dilution solution so as to prevent osmolarity shock of the red blood cells during the recovery phase. The recovered red blood cells may be suspended in a preservation solution to further increase their shelf-life following the recovery phase.Type: GrantFiled: December 7, 1998Date of Patent: July 31, 2001Assignee: Haemonetics CorporationInventor: Etienne Pages

Patent number: 6265210Abstract: Controlled atmosphere cabinet has enclosure (110;210) with means providing visibility (110F; 210F) of its interior from outside, gas supply (113-116, 212-216) for desired or target composition of internal atmosphere, controlled lock-type access (112) for manual introduction and removal of items, and hand/arm access port provision (111A, B; 211A, B) for manipulation of said samples in the cabinet. Gas supply associated control means (230-240) serves during use of the cabinet (other than normal atmosphere augmenting in use of the lock-type access) for additional gas supply further to correct or compensate for effects actually or potentially adverse to maintaining the desired or target internal atmosphere composition, via operator-actuated input means (121t, 123; 222) and/or means (122, 124, 139; 225) for sensing prescribed conditions to which the control means is responsive for said additional gas supply.Type: GrantFiled: March 8, 1999Date of Patent: July 24, 2001Assignee: Don Whitley Scientific LimitedInventors: Peter Silley, Michael John Annable

Patent number: 6248514Abstract: The instant invention addresses the need for a more accurate method of quantitating infectious viral particles in a population. The methods of the instant invention are based on the unexpected and surprising result that flow cytometry analysis of cells infected using specified ranges of viral particle concentration and/or adsorption time yields a more accurate measurement of infectious virus titer than traditional titration methods.Type: GrantFiled: August 18, 1998Date of Patent: June 19, 2001Assignee: Canji, Inc.Inventors: Beth M. Hutchins, Mary H. Nunnally, Barry J. Sugarman

Patent number: 6245342Abstract: A cosmetic preparation contains peptide derivatives from &agr;-MSH, as well as other active components. A cosmetic product has the property of activating the melanogenesis and being an anti-inflammatory and acting more efficiently. The synergetically active preparation also includes a combination of a peptide derivative corresponding to the formula (Lip)X-His-Phe-Arg-Y in a ratio of 0.05 mg to 2.5 mg of a pure peptide derivative per kg of the total mass, while the peptide derivative is mixed with xanthine in a ratio of 0.5 to 2 mol per 100 mol of peptide. Also there is at least 0.5 wt % of a mixture of enzymes and vitamins, containing at least 150 U/ml of superoxide dismutase. Also present are auxiliary agents and carrier agents in a ratio of 65 to 99.5 wt %, and possibly other active components.Type: GrantFiled: May 28, 1999Date of Patent: June 12, 2001Assignee: Lancaster Group GmbHInventors: Karin Golz-Berner, Leonhard Zastrow, Nouha Domloge

Patent number: 6242190Abstract: The present invention provides a method of rapidly screening ligands on the basis of their binding affinity and binding enthalpy by carrying out binding assays at a minimum of two temperatures. This technique permits the selection for further optimization of lead ligands that bind to the target molecules with favorable enthalpies. Those ligands will exhibit higher solubilities in aqueous solution than ligands selected by conventional means, and may exhibit lower susceptibilities to resistant mutations. The method may be utilized as a standalone technique, or may be adapted to, for example, known high throughput screening technologies. The present invention further comprises an apparatus for carrying out the described methods.Type: GrantFiled: December 1, 1999Date of Patent: June 5, 2001Assignee: John Hopkins UniversityInventors: Ernesto Freire, Matthew J.

Patent number: 6221654Abstract: The invention relates to a microfabricated device and methods of using the device for analyzing and sorting of single polynucleotides, e.g. by size, according to an optical signal measured within a detection region of the device. An optical signal such as fluorescence from a reporter molecule associated with the polynucleotide molecules can be used to determine polynucleotide size or to direct selected polynucleotides into one or more selected branch channels of the device.Type: GrantFiled: September 23, 1997Date of Patent: April 24, 2001Assignee: California Institute of TechnologyInventors: Stephen Quake, Wayne D.
