  • Difference Between Agarose and Sepharose

    Where the wells, formed by the presence of a plastic comb positioned before the polyacrylamide has set into the gel, allows the sample to be loaded. Resolving gel As the proteins migrate out of the stacking gel, into the resolving gel, they align roughly by size, thus aiding in the separation of bands containing proteins of varying size.
