Patent number: 6316613Abstract: The separation of enantiomeric pairs of compounds by capillary electrophoresis using highly sulfated &agr;-, &bgr;-, and &ggr;-cyclodextrins as chiral selectors is described herein. These charged cyclodextrins have a higher degree of sulfation and narrower heterogeneity than previous cyclodextrin derivatives. CE analyses using highly sulfated cyclodextrins produce improved resolution of a wide variety of chiral drugs, particulaly neutral compounds and amines. The highly sulfated &agr;-,&bgr;-, and &ggr;-cyclodextrins produce separations which complement each other to further expand the number of neutral and basic drugs that can be resolved by capillary electrophorsis.Type: GrantFiled: July 25, 1997Date of Patent: November 13, 2001Assignee: Beckman Coulter, Inc.Inventors: Fu-Tai A.

Patent number: 5569366Abstract: Processes for the electrophoretic analysis of monosaccharides and/or polysaccharides are disclosed. The processes generally first include providing a composition having derivatized mono and/or polysaccharide components which are monosaccharide and/or polysaccharide labelled with a fluorescing charged compound. Then introducing the composition into an electrophoretic medium and applying an electric field across the electrophoretic medium causes the derivatized monosaccharide and/or polysaccharide components to differentially migrate within the electrophoretic medium. Then detecting the derivatized monosaccharide and/or polysaccharide components is accomplished by laser exciting the derivatized monosaccharide and/or polysaccharide components and monitoring fluorescent emission of the derivatized monosaccharide and/or polysaccharide components. The processes provide extremely low detection limits of the labelled components.Type: GrantFiled: January 27, 1995Date of Patent: October 29, 1996Assignee: Beckman Instruments, Inc.Inventors: Fu-Tai A.

Patent number: 5264095Abstract: Disclosed herein is a methodology for analyzing isoenzymes using capillary zone electrophoresis ("CZE") techniques. Briefly, an isoenzyme-containing sample and a substrate capable of being catalyzed by said isoenzyme into a reaction product are introduced into a capillary column comprising a buffer. Most preferably, the buffer contains the substrate prior to introduction of the sample into such substrate-buffer. CZE separation techniques are applied to the column such that the isoenzymes are separated from each other into discrete zones. The separation techniques are terminated such that product is rapidly generated by the catalytic conversion of substrate by the isoenzymes, and accumulated, within each discrete zone, followed by detection of product. Information regarding the relative distribution of the isoenzymes can be derived from the relative distribution of the product.Type: GrantFiled: June 12, 1992Date of Patent: November 23, 1993Assignee: Beckman Instruments, Inc.Inventors: You-Zung Hseih, Fu-Tai A.
