When Analyzing Protein Multimers by Electrophoresis, Should the Samples Be Boiled?
Whether to boil protein samples prior to electrophoretic analysis depends on the nature of the multimer and the specific experimental objectives. In general, the purpose of boiling is to denature the protein and disrupt disulfide bonds, thereby dissociating multimers into monomeric subunits. This process facilitates more efficient separation and accurate identification of proteins during electrophoresis.
If the aim is to analyze the subunit composition of a multimer or to investigate the primary structure of a protein, boiling is necessary. Conversely, when the objective is to study the native multimeric state or the functional conformation of a protein, boiling should be avoided to preserve its native structure and activity.
Therefore, the decision to boil or not should be made based on the experimental purpose and the inherent characteristics of the protein under study.
