The acetic acid-urea polyacrylamide gel electrophoresis system could separate very similar basic proteins on differences in size and effective charge. This system has been used for many years to analyse histones and their post-translational modificat

The application of Design of Experiments (DoE) to the determination of optimum conditions for an extraction process relies on the correct selection of mathematical models. The linear model is the one typically used; however, in some cases it does not

In this work, a new method employing capillary electrophoresis (CE) for the determination of several species in biodiesel is introduced. The concentrations of inorganic species (Na+, K+, Ca2+, Mg2+, SO42−, and PO43−) and glycerol are of interest
