Two-dimensional gel electrophoresis image analysis of two Pseudomonas aeruginosa clones
A classical strategy to analyse the protein content of a biological sample is the two-dimensional gel electrophoresis (2D-GE). This technique separates proteins by both isoelectric point and molecular weight, and images are taken for subsequent analyses.

What Room for Two-Dimensional Gel-Based Proteomics in a Shotgun Proteomics World?
Two-dimensional gel electrophoresis was instrumental in the birth of proteomics in the late 1980s. However, it is now often considered as an outdated technique for proteomics—a thing of the past.

A Novel Spot-Enhancement Anisotropic Diffusion Method for the Improvement of Segmentation in Two-dimensional Gel Electrophoresis Images, Based on the Watershed Transform Algorithm [PDF]
Introduction Two-dimensional gel electrophoresis (2DGE) is a powerful technique in proteomics for protein separation. In this technique, spot segmentation is an essential stage, which can be challenging due to problems such as overlapping spots, streaks,

A semi-virtual two dimensional gel electrophoresis: IF–ESI LC-MS/MS
A method for increasing the productivity of ESI LC-MS/MS (electrospray ionization-liquid chromatography-tandem mass spectrometry) was proposed and applied. After IF (isoelectric focusing) of the sample using IPG (immobilized pH gradient) strip, the strip

Comparative Skeletal Muscle Proteomics Using Two-Dimensional Gel Electrophoresis
The pioneering work by Patrick H. O’Farrell established two-dimensional gel electrophoresis as one of the most important high-resolution protein separation techniques of modern biochemistry (Journal of Biological Chemistry 1975, 250, 4007–4021).

Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE): advances and perspectives
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.

Establishment of two-dimensional gel electrophoresis for soybean protein isolate and its application
To optimize the conditions for the establishment of two-dimensional gel electrophoresis (2-DE) of soybean protein isolate (SPI), we investigated Ampholine mixture, anodic and cathodic electrolytes, loading amount of sample, acrylamide concentration, pH ...

Comparative Two-Dimensional Fluorescence Gel Electrophoresis [PDF]
Abstract Comparative two-dimensional gel electrophoresis (CoFGE) is a special version of two-dimensional polyacrylamide GE (2D-PAGE) and related to difference GE (2D-DIGE). It provides reproducibility and standardisation for 2D-PAGE by introducing a reference to the experiment.
