The log of the molecular weights of proteins can be plotted against the relative mobility on SDS-PAGE. Using this plot, the relative mobility of an unknown protein can be used to estimate its molecular weight. The molecular weights are in daltons. Estimate the molecular weight (M₁) of the unknown protein that is circled on the graph. Enter the weight as a whole number.
