PULSE-FIELD MULTIPLEX CAPILLARY ELECTROPHORESIS SYSTEM
The invention is a multiplex, pulsed-field capillary electrophoresis instrument with the ability to analyze DNA fragments with sizes greater than 50,000 bp, greater than 100,000 bp and even granter than 150,000 base pairs. The parallel capillary electrophoresis system allows for the simultaneous analysis of at least 12 samples while applying a pulse or varying electric field for separation.
1 . An Electrophoresis console for multiplex pulse-field electrophoresis capable of measuring larger than 50,000 bp comprising:
a console housing an operable multiplexed capillary electrophoresis system with a multiplex capillary array; and
a pulse-field power supply for applying an alternating electric field for electrophoresis on all capillaries of said multiplex capillary array simultaneously.
2 . A pulse-field electrophoresis console to enhance workflow, comprising;
a console housing an operable pulse-field multiplexed capillary electrophoresis system;
a plurality of externally accessible drawers for holding sample plates or buffer plates in said console; and
a motion control system built within said console to move said sample plates or buffer plates from said drawers to an injection position of said multiplexed capillary electrophoresis system.
3 . The electrophoresis console of claim 2 which includes as the externally accessible drawers at least four vertically stacked drawers.
4 . The electrophoresis console of claim 2 which includes as the externally accessible drawers at least six vertically stacked drawers.
5 . The electrophoresis console of claim 2 , wherein samples can be placed into at least some of said drawers while the instrument is running and collecting electrophoresis data.
6 . The electrophoresis console of claim 2 , which includes in it an operative computer program that enables multiple users to load multiple samples into said drawers, and to run said multiple samples sequentially while the system is performing electrophoresis.
7 . In a multiplex capillary electrophoresis device, the improvement comprising:
in combination with said electrophoresis device: a pulse-field power supply; a sample loader; and a sample transporter.
8 . The multiplex capillary electrophoresis device of claim 7 , further comprising a computer controller.
9 . In an electrophoresis console which includes within it:
a capillary array with a plurality of capillaries that can be filled with an electrophoresis medium; and a fluid handling system for injecting said capillaries with said electrophoresis medium or other fluids, the improvement comprising a pulse-field power supply for applying an alternating electric field for electrophoresis on all capillaries of said capillary array simultaneously.
