| Research Abstract |
Toward the high performance separation and detection of proteins by capillary electrophoresis(CE) and microchip electrophoresis(MCE), following five subjects were mainly investigated.
1)Development of a high performance analysis method by microchip isoelectric focusing(MCIEF). Four model proteins were successfully separated within 210 s by MCIEF, where good linear relationship between a pI value of the protein and its focused position.
2)Development of a highly efficient chiral separation technique by capillary electrochromatography and microchip electrochromatography using immobilized proteins. Avidin was used as a chiral selector and four pairs of enantiomers were successfully resolved.
3)Improvement of detection sensitivity in MCE using on-line sample preconcentration. Under a micellar electrokinetic chromatography (MEKC) mode in MCE, successful on-line sample preconcentration by SRW was achieved by using a newly designed and fabricated T -cross type channel quartz chip.
4)Improvement of detectability in CE and MCE by using thermal lens microscopy (TLM). In a microchip MEKC-TLM system with sweeping as an on-line sample preconcentration technique, the limit of detection of 4 nM or 8 amol in absolute amount injected for Sunset Yellow was obtained.
5)Development of a high performance MCE system with mass spectrometric (MS) detection. An MCE-MS system with an electrospray ionization interface was developed, where some peptides and proteins were successfully separated and detected.
