These devices may include control features for regulating the micro-environment within a well or wells of the device. For example, on-board features may regulate the temperature, humidity, pH, media level, media composition, CO2/O2/N2 levels, drug concentration, cell density, byproduct (or product) production, and mixing of materials within the chamber. Material may be added to or withdrawn from the wells of the device without opening the device. Also described herein are controllers for analyzing and controlling the micro- environment within the well. Thus, the plates described herein may be used without requiring a separate incubator, allowing cells to be analyzed (e.g., imaged) continuously, allowing real-time reactions while monitoring under a microscope for hours, days or even weeks.Type: ApplicationFiled: February 7, 2007Publication date: January 14, 2010Inventors: Victor Joseph, Amjad Huda, Joseph F. Rogers

Patent number: 7640115Abstract: A method is provided to study gene function based on variations of the amino acids and the base sequences at specific positions on HLA genes which have polymorphisms and codon usage Medical industry applications for the method are also provided. The amino acid position(s) of the polymorphic amino acid(s) in amino acid sequence(s), including at least one of DRB1*gene, DQB1*gene, and DPB1*gene of HLA, is determined, the variation of the base sequences coding polymorphic positions of the amino acid and survival results with anticancer treatments after cancer resections, and survival results (prognosis, treatment effects) are analyzed, and the statistical relationship of the specific positions of the amino acids and the treatments is determined.Type: GrantFiled: October 8, 2003Date of Patent: December 29, 2009Inventor: Kyoji Ogoshi

Patent number: 7635586Abstract: Systems and methods for automatically controlling conditions of a process are disclosed. In one example, a controller is programmed with a sequence of steps and parameters required to carry out a bioreactor process. A sensor system interacts with the bioreactor to receive information related to a condition of the bioreactor and/or receive a sample from the bioreactor, which it analyzes. The sensor system sends data signals related to the information and/or the sample to a controller, which determines a control signal based on the received information. The controller sends the control signal to the sensor system which, based on the control signal, performs an action that affects a condition of the bioreactor or affects the sensor system itself.Type: GrantFiled: February 10, 2005Date of Patent: December 22, 2009Assignee: Broadley-James CorporationInventor: Larry Eugene West

Patent number: 7632653Abstract: A membrane-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes time-resolved fluorescence to detect the signals generated by excited fluorescent labels. Because the labels can have relatively long emission lifetime, short-lived background interference can be practically eliminated through delayed fluorescence detection. In addition, the resulting fluorescent reader can have a simple and inexpensive design. For instance, in one embodiment, the reader can utilize a silicon photodiode and a pulsed light-emitting diode (LED) to accurately excite labels and detect fluorescence on a membrane-based assay device without requiring the use of expensive components, such as monochromators or narrow emission band width optical filters.Type: GrantFiled: November 1, 2002Date of Patent: December 15, 2009Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Xuedong Song, Rosann Kaylor, Michael Knotts, Ning Wei
