Abstract
In this commentary, we focused our attention on capillary electrophoresis. It achieves the efficient separation of molecular species by the application of high voltages to samples in solution. Actually, capillary electrophoresis can be performed on microchip devices, based on an automated and miniaturized electrophoresis system, based on lab-on-a-chip technology. By this technology it is possible to separate nucleic acid fragments (DNA or RNA) with respect to sizing accuracy and sizing resolution. Currently, two automated capillary electrophoresis on microchips devices are available: the Agilent 2100 Bioanalyzer and the Experion™ Automated Electrophoresis System. In this study, we evaluated if the CE is able to distinguish the three uridine diphosphate glucuronosyltransferase 1A1 TATA-box genotypes.

Abstract
Nowadays, new solutions focused on the replacement of reagents hazardous to human health are highly demanded in laboratories and Green Chemistry. In the present work, GelGreen, a new nonhazardous DNA staining reagent, has been assayed for the first time to analyze double-stranded DNA by CGE with LIF detection. The effect of GelGreen concentration on S/N ratio and migration time of a wide concentration range of standard DNA mixtures was evaluated. Under optimum GelGreen concentration in the sieving buffer efficient and sensitive separations of DNA fragments with sizes from 100-500 base pairs (bp) were obtained. A comparison in terms of resolution, time of analysis, LOD, LOQ, reproducibility, sizing performance, and cost of analysis was established between two optimized CGE-LIF protocols for DNA analysis, one based on the dye YOPRO-1 (typically used for CGE-LIF of DNA fragments) and another one using the new GelGreen. Analyses using YOPRO-1 were faster than those using GelGreen (ca. 31 min versus 34 min for the analysis of 100-500 bp DNA fragments). On the other side, sensitivity using GelGreen was twofold higher than that using YOPRO-1. The cost of analysis was significantly cheaper (ninefold) using GelGreen than with YOPRO-1. The resolution values and sizing performance were not significantly different between the two dyes (e.g. both dyes allowed the separation of fragments differing in only 2 bp in the 100-200 bp range). The usefulness of the separation method using GelGreen is demonstrated by the characterization of different amplicons obtained by PCR.

Abstract
In this work, capillary electrophoresis-time-of-flight mass spectrometry (CE-TOF-MS) is proposed to identify and quantify the main metabolites found in transgenic soybean and its corresponding non-transgenic parental line both grown under identical conditions. The procedure includes optimization of metabolites extraction, separation by CE, on-line electrospray-TOF-MS analysis and data evaluation. A large number of extraction procedures and background electrolytes are tested in order to obtain a highly reproducible and sensitive analytical methodology. Using this approach, a large number of metabolites were tentatively identified based on the high mass accuracy provided by TOF-MS analyzer, together with the isotopic pattern and expected electrophoretic mobility of these compounds. In general, the same metabolites and in similar amounts were found in the conventional and transgenic variety. However, significant differences were also observed in some specific cases when the conventional variety was compared with its corresponding transgenic line. The selection of these metabolites as possible biomarkers of transgenic soybean is discussed, although a larger number of samples need to be analyzed in order to validate this point. It is concluded that metabolomic procedures based on CE-MS can open new perspectives in the study of transgenic foods in order to corroborate (or not) the equivalence with their conventional counterparts.

Abstract
This study examined the potential of microchip electrophoresis (ME) with a LIF detector using a programmed field strength gradient (PFSG) in a conventional glass double-T microchip for the ultra-fast detection and simultaneous analysis of genetically modified (GM) maize. The separation efficiency and sensitivity at various sieving gels (poly(ethylene oxide) (PEO, M(r) 8,000,000) and 2-hydroxyethylcellulose (HEC) (M(r) 250,000)) and fluorescent dye concentrations were investigated. The PCR products of both the GM and non-GM maize were analyzed within 30 s under the PFSG (470.6 V/cm for 20 s, 117.6 V/cm for 12 s, and 470.6 V/cm for 30 s) with a 2.5% HEC sieving matrix in the running buffer, 1 x Tris-borate EDTA (TBE) (pH 8.30) and 0.5 ppm ethidium bromide. The five transgenic maize varieties (Event176, MON810, Bt11, GA21, and T25) examined in this study were also clearly differentiated by ME-PFSG within 30 s in a single run without any loss of resolution. The ME-PFSG technique is a powerful tool for the ultra-fast detection and simultaneous analysis of GMOs in a variety of foods including maize.

Abstract
Nowadays, soybeans are commercialized in a wide variety of colors and tones. Moreover, some pigmented seeds are being commercialized as soybeans while, on other occasions, these seeds are labeled as mung beans, azuki beans or soybean frijoles generating confusion on their identity. In this work, CE has been applied for the first time for the characterization and differentiation of different pigmented beans commercialized as soybeans. Other seeds commercialized as azuki, mung green soybeans or soybean frijoles were also analyzed. Borate buffer (at pH 8.5) containing 20% v/v ACN was used as the separation media and solution containing ACN/water (75:25 v/v) with 0.3% v/v acetic acid was used to solubilize the proteins from the samples. A 50 cm bare fused-silica capillary was employed for obtaining adequate separations in about 12 min. The CE protein pattern observed for yellow soybeans was different from that corresponding to green and red soybeans. The seeds commercialized as black soybean presented electropherograms identical or similar to those yielded by the yellow seeds with the exception of the sample labeled as black soybeans frijoles that presented a totally different pattern. In addition, CE protein profiles obtained for azuki and mung green soybeans were very similar to those corresponding to red soybeans and green soybeans, respectively. Finally, the CE method was also applied to differentiate transgenic and nontransgenic soybean varieties. Discriminant analysis, using several protein peak areas as variable, was used to successfully classify these samples.
