The relationship between log10 (MW) [MW= Molecular weight in kDa] of a mixture of protein standards and their retension factors (Rf) obtained from native-PAGE is log10 (MW) = -2Rf + 3. If the measured retension factor for a protein with 180 amino acids is 0.5, then find the number of identical monomers in the protein.
