Nucleic Acid Gel Electrophoresis—A Brief Overview

Although agarose and agarose-polyacrylamide gels were used for separation of RNA and single-stranded DNA in the late 1960s [15,16], the work to analyze restriction-digested fragments by agarose gel electrophoresi s was not published until 1973 (Figure 3) [17,18].

what is the difference between agarose and polyacrylamide

What is the Difference Between Agarose and Polyacrylamide

The main difference between agarose and polyacrylamide is that agarose is used in the agarose gel electrophoresis (AGE) mainly for the separation of DNA, whereas polyacrylamide is used in the polyacrylamide gel electrophoresis ( PAGE) mainly for the separation of proteins. Furthermore, agarose can separate DNA fragments of 50-20,000 bp in size while polyacrylamide has a more resolving power, separating up to 5-500 bp fragments of DNA.

As the name suggests, gel electrophoresis involves a gel: a slab of Jello-like material. Gels for DNA separation are often made out of a polysaccharide called agarose, which comes as dry, powdered flakes. When the agarose is heated in a buffer (water with some salts in it) and allowed to cool, it will form a solid, slightly squishy gel.
