摘要:
Compositions containing an enzyme, a dye, and an effective amount of a surfactant selected from the group of a nonionic surfactant, a zwitterionic surfactant, and a mixture thereof and methods for processing sample materials.
摘要:
Thin film culture devices are described that have positioning structures, as well as methods for harvesting cells from colonies on the culture device based on location of colonies on the device relative to the positioning structures. In addition, a computer readable medium encoded with a computer program is described that identifies position of colonies relative to the positioning structures.
摘要:
Sample processing devices with electrophoresis channels and methods of loading the electrophoresis channels with electrophoresis sieving polymer while rotating the sample processing device are disclosed. In some instances, the electrophoresis channels may be arranged radially relative to the axis of rotation of the sample processing device. In other sample processing devices, the electrophoresis channels may be arranged in curved arcs that are concentric about the center of the sample processing device (which preferably corresponds to the axis of rotation).
摘要:
Sample processing systems and methods of using those systems for processing sample materials located in devices that are separate from the system are disclosed. The sample processing systems include a rotating base plate on which the sample processing devices are located during operation of the systems. The systems also include connection apparatus that allow for rapid and easy removal and/or replacement of base plates.
摘要:
Devices, methods, and systems for processing sample materials are disclosed. The present invention may provide a bridge between standard microtiter plate systems, methods, protocols, etc. (that include wells arranged in rectangular arrays) and rotating sample processing devices and systems that allow users to obtain the rapid processing advantages of the more advanced sample processing devices. The sample processing devices preferably include a rectangular body to improve compatibility of the sample processing devices of the present invention with equipment designed for use with more conventional microtiter plates (which are typically rectangular in shape). The sample processing devices also include at least one set of process chambers arranged in one or more circular arcs and may include input and/or output chambers arranged in a rectilinear grid array.
摘要:
Sample processing devices including process chambers having bypass slots and methods of using the same are disclosed. The bypass slots are formed in the sidewalls of the process chambers and are in fluid communication with distribution channels used to deliver fluid sample materials to the process chambers.
