So it cannot take any shortcuts because of its very small size, but because of the size of the beetle, because the beetle simply cannot fit through the different tiny pathways where the end can fit, that beetle will make its way further to the end of that grass, the patch of grass, because of its larger size. And in the same analogous way, these larger proteins, because they can't fit in the tiny pores, they can take all those different pathways that our small protein can. These large proteins will make their way to the end, to the bottom of that column first. So, once again, as a mixture of proteins travels through our column, the small proteins into the porous beads, but the larger proteins cannot fit into the internal volume of those beads. And as a result, those large proteins will end up at the bottom first, while the small proteins will emerge less. So let's see how we can actually carry out this experiment with these three different proteins by using gel filtration chromatography.
