title: A novel injection method for high-speed proteome analysis by capillary electrophoresis.
abstract: We have developed a new sample injection method for capillary electrophoresis (CE) that reduces the required migration time. We demonstrated a pressurization technique that was performed with buffer in the outlet after the electrokinetic sample injection with no buffer in the outlet. To reduce the migration time, the sample injection had to be performed with no buffer in the outlet; water should be pressurized while the buffer is in the outlet. Though the resolution was slightly decreased using this method, the addition of a separation carrier (curdlan) to the run buffer restored the resolution without delaying the migration time. The use of our new sample injection method combined with our high-quality separation carrier will enable us to improve the efficiency of the high-throughput screening (HTS) system for proteome analysis.
