In SDS-PAGE (Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis) proteins are separated on basis ofa) Massb) Chargec) Densityd) Molecular weighte) Solubility: (A) b, (B) ad, (C) ac, (D) ab
Answer is B. In SDS-PAGE the separation of molecules depends mainly on their molecular size.
Therefore, SDS-PAGE is commonly used for molecular weight determination.
