SDS-PAGE Based Protein Molecular Weights Analysis Service

Published: May 23, 2024

Molecular size variability is critically important in biological research and medical applications, serving not only in diagnosis and disease prevention but also in the quality control of bioproducts. Electrophoresis, particularly sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), is revered as the gold standard for this purpose due to its high sensitivity, ease of operation, and broad applicability.

The core of the SDS-PAGE technique lies in the action of an electric field to cause charged biomolecules to traverse the polyacrylamide gel in a size-ordered manner. This facilitates the separation of proteins and peptides of varying sizes, providing a robust tool for examining molecular structures, interactions, and aggregation states. Inaccurate protein aggregation or unexpected molecular sizes may lead to decreased biological activity, compromised drug effectiveness, or unexpected adverse effects.
