Definition of Polyacrylamide gel

Polyacrylamide is a popular choice for preparing electrophoretic gels when you need to separate proteins by size. Acrylamide is often mixed with bisacrylamide and can be prepared at different percentages depending on the size of proteins to be resolved. Low-percentage gels are used to resolve large proteins, and high-percentage gels are used to resolve small proteins.
