Cover Picture: Electrophoresis 2'2012

Issue no. 2 is a regular issue consisting of 18 contributions distributed over 5 distinct parts. The issue has an “Emphasis on Proteins and Proteomics” with 7 contributions featured in Part I. This is followed by Part II that has 4 research articles on nanopore and nanoparticles based analyses. Part III has 2 contributions on agarose gel electrophoresis for the analysis of the structure fluidity of a phage T3 DNA packaging intermediate and analyzing RNA quality. Part IV has two research articles on microchip capillary electrophoresis with poly(ethylene glycol)‐coated microfluidic devices and poly(dimethylsiloxane) microchips using a mixture of ionic and zwitterionic surfactants. The last part (Part V) consists of 3 contributions on CE of some common controlled stimulants, CE test of a blood‐brain barrier model and the simultaneous determinations of nitrite and nitrate in human plasma by CE. This issue is populated by a collection of very important research articles. It is a must read.
