Abstract
Reliable multiple single nucleotide polymorphisms (SNPs) detection at low abundance is of great significance for disease diagnosis and biomedical research. Herein, we have developed a novel and simple method for multiple SNPs detection combining solid-phase capture by specific hybridization with online preconcentration of capillary gel electrophoresis-laser-induced fluorescence (CGE-LIF). The method presents an excellent performance due to its favorable traits: the solid-phase short-chain hybridization ensures the high specificity of SNP detection; the effective separation ability of CGE can easily achieve multiplex detection; the simple online preconcentration significantly improves the detection sensitivity of fluorescent probe by nearly 100-fold. For a single SNP target, the assay achieves a limit of detection as low as 0.01-0.02% for three different NRAS mutations in the same codon. For multiple SNP targets, as low as 0.05% abundance can be easily realized. Our method is simple, efficient, ultrasensitive, and universal for multiple SNPs detection without complex enzymatic or chemical ligation reaction, which shows great potential in early clinical diagnosis.

Field-amplified sample injection in capillary zone electrophoresis for the pharmacokinetic research of trace risperidone and its major metabolite 9-hydroxyrisperidone in beagle dogs. J Sep Sci 2020; 43:3555-3564. [PMID: 32573947 DOI: 10.1002/jssc.202000252] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 06/17/2020] [Accepted: 06/17/2020] [Indexed: 11/07/2022]
Abstract
This article describes a method for the simultaneous quantitation of risperidone and its major metabolite, 9-hydroxyrisperidone, in beagle dog plasma by field-amplified sample injection in capillary zone electrophoresis. The separation was carried out at 25°C in a 48 cm × 75 µm fused-silica capillary with an applied voltage of 20 kV using 60 mM NaH2 PO4 buffer (pH 3.6). The detection wavelength was 280 nm. Clean-up and preconcentration of plasma samples were conducted by 96-well formatted liquid-liquid extraction. In this study, this stacking technique provided a sensitivity enhancement of approximately 158 to 188 fold compared with the same sample without stacking. The method was suitably validated with respect to stability, specificity, linearity, lower limit of quantitation, accuracy, precision, and extraction recovery. Calibration curves exhibited good linearity (r2 > 0.995) over a wide concentration range of 2.5 to 200 ng/mL for both risperidone and 9-hydroxyrisperidone. The intra- and interday precisions at the three quality control levels were less than 11.40%. The intra- and interday accuracies ranged from 87.90 to 107.17% for risperidone and from 88.43 to 105.92% for 9-hydroxyrisperidone. All validation data were within the required limits. In conclusion, the method developed was successfully applied to pharmacokinetic studies of risperidone and 9-hydroxyrisperidone in beagle dogs.

J Pharm Biomed Anal 2018; 156:263-271.

Abstract
This paper describes a method for quantification of d-amphetamine and diphenhydramine in beagle dog plasma by organic solvent field-amplified sample stacking (FASS)-capillary zone electrophoresis (CZE), using amlodipine as the internal standard. The separation was carried out at 25 °C in a 40.2 cm × 75 μm fused-silica capillary with an applied voltage of 20 kV using 25 mM phosphate-18.75 mM borate (pH 3.5). The detection wavelength was 200 nm. Clean-up and preconcentration of plasma biosamples were developed by 96-well formatted liquid- liquid extraction (LLE). In this study, the peak areas of d-amphetamine, diphenhydramine and amlodipine in the plasma sample increased by the factor of 48, 67 and 43 compared to the CZE without sample stacking. The method was suitably validated with respect to stability, specificity, linearity, lower limit of quantitation, accuracy, precision and extraction recovery. The calibration graph was linear from 2 to 500 ng/ml for d-amphetamine and 2-5000 ng/ml for diphenhydramine. All the validation data were within the required limits. Compared with the LC/MS/MS method that we previously established, there was no significant difference between the two methods in validation characteristics, except the LLOQs. The developed method was successfully applied to the evaluation of pharmacokinetic study of the Quick-Acting Anti-Motion Capsules (QAAMC) in beagle dogs.

Abstract
A rapid and sensitive capillary zone electrophoresis (CZE) method with field enhanced sample injection (FESI) was developed and validated for the determination of quetiapine fumarate in beagle dog plasma, with a sample pretreatment by LLE in 96-well deep format plate. The optimum separation was carried out in an uncoated 31.2 cm × 75 μm fused-silica capillary with an applied voltage of 13 kV. The electrophoretic analysis was performed by 50 mM phosphate at pH 2.5. The detection wavelength was 210 nm. Under these optimized conditions, FESI with acetonitrile enhanced the sensitivity of quetiapine about 40-50 folds in total. The method was suitably validated with respect to stability, specificity, linearity, lower limit of quantitation, accuracy, precision and extraction recovery. Using mirtazapine as an internal standard (100 ng/mL), the response of quetiapine was linear over the range of 1-1000 ng/mL. The lower limit of quantification was 1 ng/mL. The intra- and inter-day precisions for the assay were within 4.8% and 12.7%, respectively. The method represents the first application of FESI-CZE to the analysis of quetiapine fumarate in beagle dog plasma after oral administration.

Abstract
Despite the fact that extensive research in the field of separations by capillary electrophoresis (CE) has been carried out and many reviews have been published in the last years, a specific review on the use and future potential of cyclodextrins (CDs) in CE is not available. This review focuses the attention in the CD-CE topic over the January 2013-February 2014 period (not covered by previous more general CE-reviews). Recent contributions (reviews and research articles) including practical uses (e.g. solute-CD binding constant estimation and further potentials; 19% of publications), developments and applications (mainly chiral and achiral analysis; 38 and 24% of publications, respectively) are summarized in nine comprehensive tables and are commented. Statistics and predictions related to the CD-CE publications are highlighted in order to infer the current and expected research interests. Finally, trends and initiatives on CD-CE attending to real needs or practical criteria are outlined.
