Two-dimensional electrophoresis (2-DE) is one of the most commonly used techniques in proteomic investigations. However, due to the complex interplay of incidence including significant biological sample variations, lengthy steps involved in performing 2-DE as well as exposure time with silver staining, it is sometimes difficult to differentiate authentic differences caused by drug treatment with those artifacts caused by sample variations, running conditions of 2-DE as well as treatment time in silver staining etc. If we can compare pooled samples of control and treatment groups run in a single gel and stained together, we would be more comfortable with our findings. We propose here a low cost and highly effective method for locating differentially expressed proteins before and after drug treatment. This "two-in-one gel" technique might partially solve the problems mentioned above.
