Patent ID: 6929729

Claim:
A method for conducting capillary zone electrophoresis in a capillary, the method comprising: adding sodium dodecylsulfate (SDS) to a first sample to be electrophoresced; injecting the first sample into a first end of said capillary; applying a first voltage differential across said first end of said capillary and a second end of said capillary to cause said first sample to migrate in a medium suitable for capillary zone electrophoresis; adding SDS to a second sample to be electrophoresced; injecting said second sample into said first end of said capillary without rinsing said capillary with a cleaning solution intermediate the steps of applying a first voltage and injecting a second sample; and applying a second voltage differential across said first and second ends of said capillary to cause said second sample to migrate in said medium suitable for capillary zone electrophoresis.
