SDS PAGE separate molecules by size because the presence of SDS (sodium dodecyl sulphate) denatures the protein removing 2˚, 3˚ and 4˚ structures (they assume a linear chain) and the SDS coats the molecules giving them a uniform charge/mass ratio. In an experiment (SDS-PAGE) with a discontinuous buffer system following band pattern is obtained
