Patent number: 6265219Abstract: A synthesis member preferably comprises two elements: a crown and a stem. The stem includes a tag, such as a transponder, that is used to identify the synthesis member and/or the synthetic history of the synthesis member when used in the automated synthesis of compound libraries containing large numbers (e.g. 1000 or more) compounds. The crown provides the location at which compounds are synthesized. The combination of a crown for use with compound synthesis and stem allows the tracking of individual synthesis members from a library containing thousands of such synthesis members. Because each synthesis member is individually tracked and can be logged into a database and/or process flow control system, the synthesis of several thousand individual compounds in conventional containers, such as round bottom flasks is made possible using only traditional compound synthesis approaches.Type: GrantFiled: October 30, 1996Date of Patent: July 24, 2001Assignee: MitokorInventors: Rudolf Karl Andreas Giger, Henri Mattes, Andrew Malcolm Bray, Nobuyoshi Joe Maeji

Patent number: 6203990Abstract: A system and corresponding method analyzes data for patterns, such as data produced from DNA sequencers. An ASCII text file, generated by DNA sequencer software, is used as the input source for the pattern analysis software program. This text file contains peak intensity data, identified by gel-lane and mobility, for bands corresponding to 2 sequences of differing length. The software uses gel-mobility values of control DNA samples to identify bands of interest from test samples in the dataset. Spurious data point or artifacts are filtered out in this selection process. The selected data is then imported to a second software program that performs algorithms such as linear progression and curve fitting.Type: GrantFiled: April 9, 1999Date of Patent: March 20, 2001Assignee: MitoKorInventor: Eoin David Fahy
