Two-dimensional electrophoretic analysis of cytosols from human breast tumors: optimal migration conditions.
In an examination of cytosols from human breast tumors, we performed two-dimensional electrophoretic analysis. Several migration conditions were tried in a search for a homogeneous repartition of cytosolic proteins. The most workable gels were obtained with a 4.40 to 8.05 pH gradient in the first dimension and a homogeneous 125 g/L acrylamide/sodium dodecyl sulfate gel, 1 mm in thickness, in the second dimension. The practicability of this method is discussed.
