A sample of protein was run on an SDS-PAGE together with a molecular weight marker ladder. The relative mobilities of the markers and the unknown protein were calculated. The log molecular weights of the markers were plotted against their relative mobilities resulting in the following standard curve. If the relative mobility of the unknown protein was 4.2cm, calculate the molecular weight of the unknown protein.

A protein was run under native conditions in a gel filtration column and was calculated to be of 120 kDa in size. The molecular weight of the protein in SDS-PAGE was found to be 30 kDa. The oligomeric status of the protein is
