aT denotes the total percentage concentration of the monomers (acrylamide plus N,N′-methylenebisacrylamide) in grams per 100 mL. C denotes the percentage (by weight) of the cross-linker N,N′-methylenebisacrylamide relative to the total amount of monomers.
bWhen using tricine instead of glycine in running buffer (Schägger and von Jagow 1987).
cThis list is by no means exhaustive and other gel ranges may also be used.
