Abstract: A computer-implemented method for managing data snapshots among storage volumes to facilitate transitive, distributed snapshot operations such that a read request or write request can be made to any volume in a snapshot includes establishing respective snapshot tables for the volumes. Each table can correlate, for each chunk of data, a source volume and a target volume. In response to a read request for chunks in one the volumes, the respective snapshot table is accessed, and the read directed to the source volume indicated in the snapshot table. Likewise, in response to a write request for chunks in a storage volume, the table associated with the volume is accessed, and the write is directed to the target volume indicated in the table. For each chunk, the source volume is the same across all tables, such that a read or write involves no more than a single storage volume.

Abstract: The present invention involves a gel strip carrier module for a gel strip that reduces the handling of the gel strip and the hands-on-time during preparation of the gel strip for isoelectric focusing. The gel carrier module includes a gel strip chamber that serves as both a rehydration and focusing chamber, and allows the sample to be applied either throughout the entire gel or in a defined zone. The gel carrier module includes a pair of electrodes near opposite ends of the chamber that the gel strip rests on, gel side facing down. The gel carrier module includes a cover with hold-down blocks or pressure blocks to assure reliable, light contact between the gel and the electrodes during focusing. A rehydration buffer is added into the chamber, and the gel strip is gently placed in the chamber, gel side down, for rehydration.

Abstract: A cassette and electrophoretic gel assembly includes a non-conductive cassette, two solid buffer reservoirs, and an agarose gel. The assembly is disposable, and the sample wells on the gel are in standard microtiter plate format. The configuration is such that the gel is continuously in electrical contact with the electrodes in operation despite the production/migration of water and other exudates.

Abstract: An improved system for running electrophoresis gels “face up” is described. The system includes a single gel capacity strip holder, two electrodes, a sample cup, and a cover. The system provides a means of separating basic proteins on any length gel strip and the cup provides a user-friendly means of successfully putting the proteins on the gel face.

Abstract: The present invention provides a method and system for more efficiently providing a copy of a portion of a source drive of a plurality of drives in a redundant array of inexpensive disks (RAID) data storage system. The portion of the source drive includes a plurality of segments. The method and system include providing the copy of the plurality of segments from the source drive to the target drive. The plurality of segments can be modified during the step of providing the copy. The method and system further include providing another copy of a portion of the plurality of segments that have been modified since the step of providing the copy commenced if a portion of the plurality of segments have been modified since copying commenced.

Abstract: A method and system for providing a backup of a portion of a source drive of a plurality of drives in a redundant array of inexpensive disks (RAID) data storage system is disclosed. The portion of the source includes a plurality of segments. The method and system include associating the source drive with a target drive of the plurality of drives and providing a copy of the plurality of segments on the target drive. The copy is provided such that input to and output from source drive and the target drive are allowed during the step of providing the copy of the plurality of segments.

Abstract: An apparatus for efficiently circulating and moving a fluid across a workpiece. The apparatus can provide for the automated handling of the fluids used, and is well suited for use in the staining and fixing of biological assays such as electrophoresis gels. The tray of the invention includes first and second side walls, first and second end walls, a first curved wall portion connecting the first side wall and the first end wall, and a second curved wall portion connecting the second side wall and the second end wall. The inclusion of the curved surface in the combination causes mixing to occur efficiently when the tray is "rocked" from side to side as in the conventional apparatus. Thus, the apparatus of the invention may also include a motor for alternately raising and lowering each end wall of the tray in a rocking motion, thereby causing the fluid to alternately flow towards and away from each end wall.
