The analysis of corticosterone in mouse blood serum (metabolic-stress experiment) and 17-hydroxycorticosterone in human urine (exercise-stress experiment) samples by means of capillary electrophoresis/UV absorbance in conjunction with online sample concentration techniques is described. The use of normal MEKC had an analyte detection limit of 7 microg/ml (S/N=3); whereas when online sample conc...

The popularity of micro-Total Analysis Systems (μ-TAS) is exponentially increasing, especially in the fields of medical and biological analyses. The work presented here includes 2-D separation of proteins in PMMA-based microchips. Sodium Dodecyl Sulfate Capillary Gel Electrophoresis (SDS-CGE) and Micellar Electrokinetic Chromatography (MEKC) were used as the separation scheme for the first and ...
