what is sds polyacrylamide gel electrophoresis

SDS-PAGE (Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis) is a specialized form of PAGE that uses SDS, a detergent that denatures proteins and imparts a uniform negative charge to them. This ensures that proteins are separated based on their molecular weight alone, making it an essential tool for protein analysis and molecular weight determination.
