Analysis Note

The large pore diameter of Discovery BIO PolyMA-SCX and PolyMA-WAX particles allows full access to small peptides and very large proteins and protein aggregates. This Figure shows the power of ion-exchange to resolve proteins with very little difference in molecular weight, an advantage over size-exclusion separations.
