چکیده

The recent trend in science is to assay as many biological molecules as possible within a single experiment. This trend is evident in proteomics where the aim is to characterize thousands of proteins within cells, tissues, and organisms. While advances in mass spectrometry have been critical, developments made in two-dimensional PAGE (2D-PAGE) have also played a major role in enabling proteomics. In this review, we discuss and highlight the advances made in 2D-PAGE over the past 25 years that have made it a foundational tool in proteomic research.

A Simpler and Faster Version of Two-Dimensional Gel Electrophoresis Using Vertical, Mini SDS-PAGE Apparatus

We have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-DE). This modified version of 2-DE is not only simpler and easier but also faster than all the currently available methods. In this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrop...

Multiple SDS-PAGE on Vertical Electrophoresis Units.

INTRODUCTION SDS-polyacrylamide gel electrophoresis (SDS-PAGE) represents the second-dimension separation of two-dimensional (2D)-PAGE. Large-scale proteome analysis usually requires simultaneous electrophoresis of batches of second-dimension SDS-PAGE gels to maximize the reproducibility of 2D electrophoresis protein profiles. This requirement is most easily met using multiple, vertical second-...
