The reason that certain protein has an apparent molecular mass of 90KD when determined by the gel filtration and 60kD when determined by SDS-PAGE in the presence or absence of 2-mercaptoethanol. Concept introduction: Gel filtration is a technique used for the separation of molecules based on the molecular size. In these techniques, molecules move through the porous of beads, diffusing into the beads with greater or lesser degrees of interaction. Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) analyzes the protein mixture based on size. Proteins that have higher and lower molecular mass run slowly and fast in the gel under the effect of an electric field respectively.
