2-DE is a powerful protein analytical tool whose major strengths include semiglobal quantitation and charge separation of complex protein mixtures, enabling the analysis of differential protein expression, and variable post-translational modification. One of 2-DE's limitations relates to its limited dynamic range and consequently the number of proteins expressed that can be analyzed on a single gel. In an attempt to improve the yield of detectable proteins during sample preparation, we applied a novel extraction technique called pressure cycling technology.
