Abstract: An automated capillary zone electrophoretic system is disclosed. The system employs a capillary cartridge having a plurality of capillary tubes. The cartridge has a first array of capillary ends projecting from one side of a plate. The first array of capillary ends are spaced apart in substantially the same manner as the wells of a microtitre tray of standard size. This allows one to simultaneously perform capillary electrophoresis on samples present in each of the wells of the tray. The system includes a stacked, dual carrousel arrangement to eliminate cross-contamination resulting from reuse of the same buffer tray on consecutive executions from electrophoresis. The system also has a container connected to the detection end of the capillaries. The container is provided with valving which facilitate cleaning the capillaries, loading buffer into the capillaries, introducing samples to be electrophoresced into the capillaries, and performing capillary zone electrophoresis on the thus introduced samples.

The system also has a gel delivery module containing a gel syringe/a stepper motor or a high pressure chamber with a pump to quickly and uniformly deliver gel through the capillary tubes. The system further includes a multi-wavelength beam generator to generate a laser beam which produces a beam with a wide range of wavelengths. An off-line capillary reconditioner thoroughly cleans a capillary cartridge to enable simultaneous execution of electrophoresis with another capillary cartridge. The streamlined nature of the off-line capillary reconditioner offers the advantage of increased system throughput with a minimal increase in system cost.

Abstract: The present invention relates to a method for determining the presence of a mutation in a first sample comprising first polynucleotides. The reference sample comprises reference polynucleotides. The first sample and a reference sample are subjected to electrophoresis in the presence of at least one intercalating dye. During electrophoresis the temperature of the first sample and the reference sample is changed by an amount sufficient to change an electrophoretic mobility of at least one of the first or reference polynucleotides. Fluorescence intensity data are obtained. The fluorescence intensity data are indicative of the presence of the first and reference polynucleotides. The data are processed to determine the presence of mutation in the first polynucleotides.

Abstract: The invention provides a side-entry optical excitation geometry for use in a multiplexed capillary electrophoresis system. A charge-injection device is optically coupled to capillaries in the array such that the interior of a capillary is imaged onto only one pixel. In Sanger-type 4-label DNA sequencing reactions, nucleotide identification ("base calling") is improved by using two long-pass filters to split fluorescence emission into two emission channels. A binary poly(ethyleneoxide) matrix is used in the electrophoretic separations.

Abstract: A statistical system is disclosed to analyze multivariate response of circadian rhythms in a crossover design, in which response variables are continuously monitored to evaluate the therapeutic effect of a regimen on circadian rhythms such as blood pressure and blood sugar. The methods determine the alteration of not only amplitude but also correlation of multiple circadian rhythms under the influence of a regimen.

Abstract: A capillary electrophoresis system comprises capillaries positioned in parallel to each other forming a plane. The capillaries are configured to allow samples to migrate. A light source is configured to illuminate the capillaries and the samples therein. This causes the samples to emit light. A lens is configured to receive the light emitted by the samples and positioned directly over a first group of the capillaries and obliquely over a second group of the capillaries. The light source is further configured to illuminate the second group of capillaries more than the first group of the capillaries such that amount of light received by the lens from the first group of capillaries is substantially identical to amount of light received from the second group of capillaries when an identical amount of the samples is migrating through the first and second group capillaries.
