The aim of this exercise is to use your knowledge of standard curves and SDS-PAGE to find the most likely composition of a protein complex.
Determine the most likely composition of the protein complex from the data provided. Use the rainbow marker in the first lane to determine the approximate molecular masses of the bands observed in lane 1 and 2, respectively. Hint: Generate a standard curve for the rainbow marker first. Remember to plot the logarithm of the band size on the x-axis.
