Peptides can be separated using an ion-exchange column based on their isoelectric (pl) values. At which pH values would two different peptides, one with a pl of 5.0 and the other with a pl of 9.2, bind to a cation- and anion-exchange column? Each peptide may be capable of binding to each column at more than one pH value. anion-exchange column at pH = 3.0 cation-exchange column at pH = 3.0 Answer Bank peptide B pI = 9.2 peptide A...
