Shibukawa et al. (40) discussed the frontal analysis method, also called high-performance frontal analysis (HPFA) or high-performance capillary electrophoresis/frontal analysis (HPCE/FA), compared it to conventional methods, and focused on the application to stereoselective protein binding. The affinity of the drugs warfarin, verapamil, and carbamazepine and the drug candidate BOF-4272 to HSA was investigated.

In the previously described electrophoretic methods, the capillary was filled with electrolytes only. Another mode of operation in capillary electrophoresis involves filling the capillary with gel or viscous polymer solutions. If desired, a column can be packed with particles and equipped with a frit.68 This mode of analysis has been favorably used for the size determination of biologically important polymers, such as DNA, proteins, and polysaccharides. The most frequently used polymers in capillary gel electrophoresis are cross-linked or linear polyacrylamide,69 cellulose derivatives,70-75 agarose,76 78 and polyethylene glycols.

FIGURE 15.4 Computer record of a two-dimensional capillary electrophoresis analysis of a protein homogenate prepared from ahiopsy obtained from the fundus of a Barrett s esophagus patient. The data were generated hy performing 1 s transfers between capillaries and a 9 s second-dimension separation. The first-dimension separation employed the same buffer as the CSE separation in Fig. 15.1 and the second-dimension separation employed the same buffer as the MECC separation in Fig. 15.1.
