What is polyacrylamide gel electrophoresis?

Electrophoretic mobility is a function of the length, conformation, and charge of the molecule. Polyacrylamide gel electrophoresis is a powerful tool used to analyze RNA samples. When polyacrylamide gel is denatured after electrophoresis, it provides information on the sample composition of the RNA species.

What is the difference between agarose gel and polyacrylamide gel?

Agarose gels can be used to resolve large fragments of DNA. Polyacrylamide gels are used to separate shorter nucleic acids, generally in the range of 1−1000 base pairs, based on the concentration used (Figure 1). These gels can be run with or without a denaturant. Gels that are run without a denaturant are referred to as native gels.

What are polyacrylamide gels?

Polyacrylamide gels are a matrix of cross-linked acrylamide monomers with the tightness of the mesh dependent upon the amount of acrylamide and cross-linker present. Different sized proteins therefore require different formulations of acrylamide gel to achieve optimum separation (table 1).

What glycerol buffer should I use for a polyacrylamide gel?

For nondenaturing gels, use the 5x glycerol sample loading buffer. Be sure to wash buffer out of the wells using a syringe immediately before loading the gel. For sharp bands, you should load to much less than the maximum well volume. You will need a high voltage power supply to run the large vertical polyacrylamide gels.

Which pore size is needed for polyacrylamide gel?

Generally the larger the protein the larger pore size is needed in the polyacrylamide gel and the smaller the protein the smaller the pore size (table 1). Once the gel concentration needed has been identified these can either be purchased as pre-cast gels or made in the laboratory using the recipe in table 2. Table 2.
