So here we have the electrophoresis setup. We basically take the mixture of these two proteins, we put them inside the well and we wait some time. And what will happen is, because this has a greater size, it will experience a greater resistance as it travels down to the bottom of our gel. And so what happens is after some time passes, this will migrate less than the smaller green protein. And so we're going to form two bands. One of the band, the green band, corresponds to this protein and the second band corresponds to this larger polypeptide chain.
