Comparative two dimensional fluorescent electrophoresis (CoFGE)

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 Chemistry1975, 250, 4007-4021). The application of two-dimensional gel electrophoresis has played a key role in the systematic identification and detailed characterization of the prote...

pI-Control in Comparative Fluorescence Gel Electrophoresis (CoFGE) using amphoteric azo dyes

Amphoteric azo dyes were used for internal control of pI values in Comparative two-dimensional Fluorescence Gel Electrophoresis (CoFGE) [1]. The 2D-gel images of separated Escherichia coli proteins as well as those of colored amphoteric dyes separated by isoelectric focussing are presented. The latter were used to correct for variation in the first electrophoretic dimension and further improve ...

Two-dimensional Electrophoresis

Two-dimensional (2D) polyacrylamide gel electrophoresis is a classical technique for the separation of proteins. It Rrst appeared in the mid-1970s but for a long time it only found limited applications. Recently it has enjoyed an impressive renaissance. The major reasons for this are the introduction of the immobilized pH gradient (IPG) strips and the development of analytical methods capable o...

Two-Dimensional Electrophoresis

We compared cellular proteins from normal human blood lymphocytes, monocytes, and granulocytes, using highresolution two-dimensional electrophoresis. The leukocytes were isolated from peripheral blood by centrifugation on density step gradients (yielding a fraction of purified granulocytes and a lymphocyte/monocyte mixture) and monocytes were subsequently separated from lymphocytes by virtue of...
