Protein electrophoresis separates proteins in a polyacrylamide gel under an electric field; in SDS-PAGE, sodium dodecyl sulfate denatures proteins and gives them a broadly similar negative charge-to-mass ratio, so migration mainly reflects apparent molecular mass through the gel matrix. The readout is a stained protein band pattern: band position estimates apparent molecular mass using protein standards, band intensity reflects relative protein abundance within the linear range of staining/detection, and changes in band pattern can reflect protein expression, degradation, purification, or sample composition.
Protein Electrophoresis
Protein electrophoresis is a key technology for separating and analyzing proteins. It uses an electric field to move proteins in a gel to separate molecules with similar sizes and different charges. This method can be used to study protein structure, detect protein content, verify protein purity, and help identify disease markers. Protein electrophoresis is widely used in the fields of molecular biology, biochemistry and clinical research, providing scientists with an effective means to deeply explore protein functions and interactions.
