    laboratory technique for separating proteins by size using an electric current

    SDS-PAGE, or Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis, is a laboratory technique used to separate proteins based on their size. By applying an electric current, proteins treated with SDS (which gives them a uniform negative charge) move through a gel matrix, allowing researchers to analyze the protein composition of a sample.
