What does PAGE stand for in electrophoresis terminology?

• A. Polyacrylamide Gel Electrophoresis
• B. Polyacrylamide Gel Elution
• C. Polyacrylamide Gels for Electrophoresis
• D. Protein Anion Gel Electrophoresis

Answer: (A)

PAGE stands for Polyacrylamide Gel Electrophoresis. In this approach, proteins (or other charged molecules) migrate through a gel made of polyacrylamide when an electric field is applied. The gel’s porous network acts like a sieve, so smaller proteins move faster and larger ones move more slowly, giving high-resolution separation by size. The term is used whether the proteins are denatured (as in SDS-PAGE) or analyzed in their native state, depending on the experiment. The other options don’t capture the material of the gel (polyacrylamide) and the technique (electrophoresis) together, or they describe a different concept altogether, so they aren’t the standard name for this method.
