    摘要: An electrophoretic system having a plurality of separation lanes is provided with an automatic color calibration feature in which each lane is separately calibrated. For each lane, a dye matrix standard is created using reference fragments which migrate either before, or after, the sample fragments being electrophoresced, during the same electrophoresis run. These dye standards are detected automatically for the purpose of determining coefficients used to identify sample fragments mixed together with the reference fragments. This allows for calibrating the dye standard matrix for each of a plurality of lanes each time the electrophoresis system is used.

    摘要: 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 is 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 electrophoresed into the capillaries, and performing capillary zone electrophoresis on the thus introduced samples.

    摘要: According to a method of determining a size of a sample polynucleotide, a sample polynucleotide is subjected to electrophoresis in the presence of a fluorescent compound having a first fluorescence spectrum. Detection of light of the first fluorescence spectrum is indicative of the presence of the sample polynucleotide. One or more size standards are also subjected to electrophoresis, optionally in the presence of the sample polynucleotide. If more than one size standard is used, the different size standards typically have different mobilities. The size standards are generally essentially or completely free of polynucleotides. Migration coordinates, e.g., migration times, of the sample polynucleotide and size standard(s) are determined. A size of the sample polynucleotide can be determined using the migration coordinate of the sample polynucleotide and the migration coordinate(s) of the size standard(s).

    摘要: An acoustic displacement flowmeter for determining flow rate of a fluid has a fluid flow line defining a flow path for the fluid. The fluid flow line has an inlet and an outlet. A controllable valve is positioned along the fluid flow line for opening and closing the flow path as desired, and an acoustic displacement transducer having a fluid port is coupled to the fluid flow line upstream from the controllable valve. The outlet of the fluid flow line extends through a wall isolating fluid exhausted from the outlet of the fluid flow line from electrical and/or mechanical components residing inside the flowmeter, thereby preventing the exhausted fluid, if explosive, from contacting such electrical and/or mechanical components which may act as potential ignition sources. Preferably, a manifold having a rigid body is provided in which the fluid flow line is formed. An acoustic displacement transducer (ADT) chamber wall is formed on the manifold body, and has an ADT chamber inlet port formed therein, and the fluid flow line has a branched portion connecting the fluid flow line to the ADT chamber inlet port. The outlet of the fluid flow line extends through a wall formed in the manifold body to isolate fluid exhausted from the outlet of the fluid flow line from electrical and/or mechanical components residing inside the flowmeter.

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 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.
