Abstract
Recently, the in-capillary electrophoresis assay has been applied to variety kinds of analyses owing to its multiple functional integrating features, including mixing of samples, reaction process of the mixtures, and the separation and detection in one capillary system. However, the micro-reactor still has its limitations to the currently available applications, especially the mixing step of the samples inside the capillary could not be well controlled automatically or manually. Herein, we have developed a novel capillary electrophoresis assay for the detection of antibody-peptide binding inside a bending capillary. Its efficacy was monitored using an anti-FLAG M2 antibody and its ligand conjugated with FAM dye (FAM-DYKD). The antibody and the peptide were mixed inside the bending capillary with sequential injections. It was found that the numbers of semi-circle on the capillary interfered by the antibody and peptide binding dynamic. Additionally, an online competition assay was performed, which further validated the efficacy of the bending capillary device on monitoring the dynamic binding between the antigen and antibody. In summary, our data suggests that the novel assay is a practical approach in monitoring the antibody-antigen complex formation at a nano-scale. It could be applied to detect any biomolecule-biomolecule interaction as a general strategy.

Abstract
The review brings a comprehensive overview of recent developments and applications of high performance capillary and microchip electroseparation methods (zone electrophoresis, isotachophoresis, isoelectric focusing, affinity electrophoresis, electrokinetic chromatography, and electrochromatography) to analysis, microscale isolation, purification, and physicochemical and biochemical characterization of peptides in the years 2015, 2016, and ca. up to the middle of 2017. Advances in the investigation of electromigration properties of peptides and in the methodology of their analysis (sample preseparation, preconcentration and derivatization, adsorption suppression and EOF control, and detection) are described. New developments in particular CE and CEC methods are presented and several types of their applications to peptide analysis are reported: qualitative and quantitative analysis, determination in complex (bio)matrices, monitoring of chemical and enzymatical reactions and physical changes, amino acid, sequence and chiral analysis, and peptide mapping of proteins. Some micropreparative peptide separations are shown and capabilities of CE and CEC methods to provide important physicochemical characteristics of peptides are demonstrated.

Novel application of fluorescence coupled capillary electrophoresis to resolve the interaction between the G-quadruplex aptamer and thrombin. J Sep Sci 2017; 40:3161-3167.

Abstract
The dynamic binding status between the thrombin and its G-quadruplex aptamers and the stability of its interaction partners were probed using our previously established fluorescence-coupled capillary electrophoresis method. A 29-nucleic acid thrombin binding aptamer was chosen as a model to study its binding affinity with the thrombin ligand. First, the effects of the cations on the formation of G-quadruplex from unstructured 29-nucleic acid thrombin binding aptamer were examined. Second, the rapid binding kinetics between the thrombin and 6-carboxyfluorescein labeled G-quadruplex aptamer was measured. Third, the stability of G-quadruplex aptamer-thrombin complex was also examined in the presence of the interfering species. Remarkably, it was found that the complementary strand of 29-nucleic acid thrombin binding aptamer could compete with G-quadruplex aptamer and thus disassociated the G-quadruplex structure into an unstructured aptamer. These data suggest that our in-house established fluorescence-coupled capillary electrophoresis assay could be applied to binding studies of the G-quadruplex aptamers, thrombin, and their ligands, while overcoming the complicated and costly approaches currently available.

Abstract
Herein, a Förster resonance energy transfer system was designed, which consisted of CdSe/ZnS quantum dots donor and mCherry fluorescent protein acceptor. The quantum dots and the mCherry proteins were conjugated to permit Förster resonance energy transfer. Capillary electrophoresis with fluorescence detection was used for the analyses for the described system. The quantum dots and mCherry were sequentially injected into the capillary, while the real-time fluorescence signal of donor and acceptor was simultaneously monitored by two channels with fixed wavelength detectors. An effective separation of complexes from free donor and acceptor was achieved. Results showed quantum dots and hexahistidine tagged mCherry had high affinity and the assembly was affected by His6 -mCherry/quantum dot molar ratio. The kinetics of the self-assembly was calculated using the Hill equation. The microscopic dissociation constant values for out of- and in-capillary assays were 10.49 and 23.39 μM, respectively. The capillary electrophoresis with fluorescence detection that monitored ligands competition assay further delineated the different binding capacities of histidine containing peptide ligands for binding sites on quantum dots. This work demonstrated a novel approach for the improvement of Förster resonance energy transfer for higher efficiency, increased sensitivity, intuitionistic observation, and low sample requirements of the in-capillary probing system.
