Polyacrylamide gel electrophoresis (PAGE) is probably the most common analytical technique used to separate and characterize proteins. Each method has many variations with individual advantages and limita. Celis, Danish Centre for Human Genome Research.

Polyacrylamide gel electrophoresis (PAGE) is a technique widely used in biochemistry, forensic chemistry, genetics, molecular biology and biotechnology to separate biological macromolecules, usually proteins or nucleic acids, according to their electrophoretic mobility. Usually proteins are separated by polyacrylamide gel electrophoresis (PAGE) in the presence of a detergent and under (heat-) denaturing and (non- or) reducing conditions. Polyacrylamide gel electrophoresis (PAGE) is a technique use almost universally in life science laboratories.

Gel electrophoresis is used to separate macromolecules like DNA, RNA and proteins. The nature of the separation depends on the treatment of the sample and the nature of the gel. Native gel electrophoresis usually attempts to keep RNA or protein in its native structure while running it through the gel.

This is turned into heat, and heat has several negative implications in electrophoresis. For example, capillary Gel Electrophoresis (cGE) provides detailed information about the relative impurity content and the purity of an analyte. Separation of proteins may be by isoelectric point (pI), molecular weight, electric charge, or a combination of these factors.

You'll load all of these molecules onto your protein gel, but in the end you'll see only the proteins because you'll use a protein-specific stain. Denaturing gel electrophoresis attempts to reduce the RNA or protein into its most linear structure before or during gel electrophoresis. While in SDS-PAGE the electrophoretic mobility of proteins depends primarily on their molecular mass, in native PAGE the mobility depends on both the protein's charge and its hydrodynamic size.

Gel sizes range from 2 x 3 cm (tiny) to 15 x 18 cm (large format). Protein electrophoresis is a method for analysing the proteins in a fluid or an extract. This allows them to be measured and analyzed individually.

As the electric field is applied, each sample component migrates according to its own mobility in a gel medium of constant pH and ionic strength.

Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa. The anode and cathode solutions were 10mM phosphoric acid and histidine, respectively. SDS Page is a type of gel electrophoresis which is used to separate proteins from a protein mixture based on their sizes.

However, classical modes of detection (including dye staining, immunoreaction with antisera, and autoradiography) do not allow the detection of metal–protein complexes. In native PAGE electrophoresis most proteins have an acidic or slightly basic pl (isoelectric point) (~3–8) and migrate towards the negative polar. "Native" or "non-denaturing" gel electrophoresis is run in the absence of SDS.

As proteins move through a gel in response to an electric field, the smaller molecules travel more rapidly than larger proteins (see figure below). Medium-sized gels (8 x 13 cm) are called midi gels. This is a very useful way to determine a protein.
