To meet the research needs of analyzing the purity of protein products, MtoZ Biolabs has developed and optimized a SDS-PAGE based workflow, and provides an accurate analytical service for protein/peptide purification study.

Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is a technology commonly used in protein purification and analysis. SDS-PAGE can separate proteins according to the differences in the charge and the different mobility due to different molecular sizes. If the protein sample has been highly purified and contains only one protein, the results would show a single protein band after SDS-PAGE separation. However, when there are multiple proteins in the protein samples, different proteins can be separated into multiple protein bands through SDS-PAGE. Therefore, SDS-PAGE technology provides a direct way to analyze the purity of protein samples. To meet the research needs of analyzing the purity of protein products, MtoZ Biolabs has developed and optimized a SDS-PAGE based workflow, and provides an accurate analytical service for protein/peptide purification study.

Analytical Principles of SDS-PAGE

SDS is a type of anionic surfactant that can break the hydrogen and hydrophobic bonds in proteins. SDS can bind to proteins in a certain proportion to form SDS-protein complexes, covering the intrinsic charges of proteins. Therefore, the migration speed of all kinds of SDS-protein complexes is only determined by the molecular weight of proteins. Different proteins are separated by SDS-PAGE electrophoresis, followed by protein staining and analysis of protein bands.
