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.

A monoclonal antibody binds to threonine 49 in the non-structural 1 protein of influenza A virus and interferes with its ability to modulate viral replication. Antiviral Res 2015; 116:55-61.

Abstract
The emergence of resistant influenza A viruses highlights the continuous requirement of new antiviral drugs that can treat the viral infection. Non-structural 1 (NS1) protein, an indispensable component for efficient virus replication, can be used as a potential target for generating new antiviral agents. Here, we study the interaction of 2H6 monoclonal antibody with NS1 protein and also determine whether influenza virus replication can be inhibited by blocking NS1. The 2H6-antigen binding fragment (Fab) forms a multimeric complex with the NS1 RNA-binding domain (RBD). T49, a residue which forms a direct hydrogen bond with double stranded RNA, in NS1 protein was found to be critical for its interaction with 2H6 antibody. NS1(RBD) has high affinity to 2H6 with KD of 43.5±4.24nM whereas NS1(RBD)-T49A has more than 250 times lower affinity towards 2H6. Interestingly, the intracellular expression of 2H6-single-chain variable fragment (scFv) in mammalian cells caused a reduction in viral growth and the M1 viral protein level was significantly reduced in 2H6-scFv transfected cells in comparison to vector transfected cells at 12h post infection. These results indicate that the tight binding of 2H6 to NS1 could lead to reduction in viral replication and release of progeny virus. In future, 2H6 antibody in combination with other neutralizing antibodies can be used to increase the potency of viral inhibition.

Abstract
A numerical simulation of the direct zonal liquid chromatographic method is described for studying the binding of a ligand to a macromolecule by quantification of the interacting species present in a sample at equilibrium. The algorithm accounts for both the kinetic exchanges in solution and the dispersion effects depicted by the Fick law. Dimensionless variables are used for the concentrations which are expressed as a function of the equilibrium constant, KD. The free ligand concentration was varied in the injected samples from 0.1 to 20 KD, while that of the macromolecule was kept constant. An apparent binding isotherm was obtained from the total ligand chromatogram generated by the simulation run, when the amount emerging at almost column dead volume is plotted against that eluting at the free ligand retention time. As a continuous dissociation of the complex may occur during its migration, the apparent binding curve and the theoretical binding isotherm coincide at extremely low dissociating rates. At larger dissociation rates (0.001 s(-1) < kd <0.1 s(-1), for a first peak eluting in 1 min) the simulations were used to test various chromatographic conditions. The flow rate (or column volume) is the major effect which influences the on-column dissociation process as an exponential decay was found when the apparently bound fraction is plotted against the analysis time. The apparent equilibrium coefficient is close to the theoretical one for a binding curve generated with an initial solution containing a relatively low total concentration of binding sites (< or = KD). The apparent stoichiometric term is largely underestimated as its value decreases exponentially at increasing dissociation rates. An extrapolation at extremely short analysis times could be used to determine the stoichiometric coefficient characterizing the binding interaction.

Abstract
The binding of an anticancer drug (actinomycin D or ACTD) to double-stranded DNA (dsDNA) was studied by means of high-performance liquid chromatography (HPLC). ACTD is an antitumor antibiotic containing one chromophore group and two pentapeptidic lactone cycles that binds dsDNA. Incubations of ACTD with DNA were performed at physiological pH. The complexed and free ligand concentrations of the mixture were quantified at 440 nm from their separation on a size-exclusion chromatographic (SEC) column using the same buffer for the elution and the sample incubation. The DNA and the ACTD-DNA complexes were eluted at the column exclusion volume while the ligand was retained on the support. An apparent binding curve was obtained by plotting the amount emerging at the exclusion column volume against that eluted at free ACTD retention volume. A dissociating effect was evidenced and the binding parameters were significantly different from those obtained at equilibrium by visible absorbance titration. The equilibrium binding parameters determined by absorption spectroscopy were used as starting data in the numerical simulations of the chromatographic process. The results showed a strong dependency of the apparent binding parameters on the reaction kinetics. Finally the comparison of the apparent binding curve obtained from the HPLC experiments and from the numerical simulations permitted an evaluation of the dissociation rate constant (kd = 0.004 s(-1)).

Abstract
Analysis of antibody-antigen interactions using size-exclusion high-performance (pressure) liquid chromatography was applied to a polyvalent system composed of both reactive and nonreactive components. Mixtures containing varying concentrations of antivenin (Crotalidae) polyvalent (equine origin) and either Crotalus atrox (Western diamondback rattlesnake) venom (CV) or isolated C. atrox phospholipase A2 (PLA2) were separated using a Bio-Sil SEC 250-5 size-exclusion column (300 x 7.8 mm). Major regions containing high-molecular-weight aggregates, antivenin IgG, and CV components or PLA2 could be identified from the elution profiles. Changes in elution profile areas could be modeled by equations derived from the law of mass action that included values for the maximum fraction of reactivity, antigen valence, apparent binding constants, profile area proportionality constants, and nonreactive profile area. The analysis was simple, fast, and readily interpretable and may be applicable to a variety of situations in which stable antigen-antibody complexes are formed in the presence of nonreactive components.
