Abstract: | The isolation and characterization of protein complexes are essential steps toward understanding cellular functions. A method for separating and characterizing high-molecular-weight protein complexes using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) with native agarose gel isoelectric focusing (IEF) is described. Using this method, fractions containing high-molecular-weight protein complexes were analyzed. The advantages of using native agarose gel IEF include the ability to concentrate the protein complexes and the ease of handling when performing 2D separations. Although limited with respect to the size of molecules and particles that may be separated, this method is useful for the isolation and characterization of high-molecular-weight protein complexes. |
