The following question are based on the following proteins: list the proteins in the order of first to the last that eluted out from a size exclusion column list the proteins in the order of first to the last that eluted out from a cation exchanger column Predict the relative position of the proteins if they are subjected to SDS-PAGe in the following figure Draw relative positions of the proteins after the mixture of the four proteins applied to two dimensional gel electrophoresis: isoelectric focusing is applied in the x axis: SDS-PAGE is applied in the y-axis.
