Electrophoresis is a powerful separation technique, however the technique only gives a crude estimate of molecular weight and identity. It is often used in sequence with other more precise methods. In proteomics, enzymatic digestion is often performed on specific separated protein bands excised from the gel to get a more accurate identification of the protein by mass spectrometry.

Thus, the evolutionary process has used the principles of patchy colloid theory. We used sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) to characterize the protein molecular.

Electrophoresis is a commonly used technique in bioanalytical chemistry. In gel electrophoresis, molecules migrate through a gel medium according to their charge (applied by the electrodes). In the case of proteins, charge is proportional to mass and therefore molecular weight resolution is achieved.
