U.V. scanning may readily be performed on unstained agar-gel strips in the dry state. Polyacrylamide gels tend to become brittle if dried; whether they can be reliably scanned in the undried state, as unstained strips or columns, depends on whether t

The electrophoretic mobility is dependent on external factors like electric field strength, viscosity, gel concentration and temperature, and intrinsic proper- ties of the molecule like charge density, size and hydrophobicity. While proteins can be s
