<unk>  separated by SDS-PAGE, Coomassie brilliant blue staining<unk> unk>  is a method for analysing the<unk>  in a fluid or an extract. The<unk>  may be performed with a small volume of sample in a number of alternative ways with or without a supporting medium: SDS polyacrylamide<unk><unk>  (in short:<unk><unk> , PAGE, or SDS-electrophoresis), free-flow<unk> , electrofocusing, isotachophoresis, affinity<unk> , immunoelectrophoresis, counterelectrophoresis, and capillary<unk> . Each method has many variations with individual advantages and limitations.<unk><unk>  is often performed in combination with electroblotting immunoblotting to give additional information about a specific<unk>  Because of practical limitations,<unk> unk>  is generally not suited as a preparative method.
