Restriction mapping is one of the essential steps in gene analysis and molecular biology studies. Slab gel electrophoresis is the traditional way to separate DNA fragments for restriction mapping. However, slab gel electrophoresis does not provide sufficient resolution as required in many mapping applications, and the use of radioisotopes in traditional mapping methods creates health hazards. I...

BACKGROUND Hemoglobin (Hb) A1c is widely used as the gold standard for blood glucose level monitoring in diabetic patients. Various methods are being used in clinical laboratories for HbA1c measurement. However, the presence of Hb variants may interfere with HbA1c measurement. METHODS The HbA1c assay was performed routinely in a 55-year old woman with type 2 diabetes and hyperlipidemia that w...

We report an improved interface for two-dimensional capillary electrophoresis. This interface is based on capillary tubing and a Plexiglas chip, both of which were milled using a micro-dicing saw. The interface was evaluated and compared to a traditional interface design for both pseudo one-dimensional and two-dimensional capillary electrophoresis. We observe less than 70% transfer efficiency f...

Deproteinisation with acetonitrile (along with methanol or other reagents) is a useful and rapid technique in analysis of drugs or their metabolites in human serum. In this paper application of this simple technique in biopharmaceutical analysis using capillary electrophoresis (CE) is evaluated. Some drugs with different ionic and protein binding properties were selected and dissolved in human ...

Until now, all methods for temperature sensing in capillary electrophoresis (CE) relied on molecular probes with temperature-dependent spectral/optical properties. Here we introduce a nonspectroscopic approach to determining temperature in CE. It is based on measuring a temperature-dependent rate constant of complex dissociation by means of a kinetic CE method known as nonequilibrium capillary ...
