Sample preparation and solubilization are crucial factors for the overall performance of the 2-D PAGE technique. Protein complexes and aggregates should be completely disrupted in order to avoid appearance of new spots due to a partial protein solubilization. The SWISS-2DPAGE samples were prepared as followed:Human samplesCEC (Colon epithelial cell): Within a maximum of 30 min, a large right or left colon tissue samp......閱讀全文
