in proteomics
initialism: PAGE

Separation technique used to separate or fractionate proteins and larger peptides according to their relative molecular mass using an electric field in polyacrylamide gel (PAGE).
Note: 1D PAGE has two basic modes: a denaturing (or SDS) PAGE to estimate relative molecular masses and a native PAGE to separate proteins as their native structures.
