Selectivity

 

Separation of Insulin Analogs:
  Closely related peptides can be difficult to separate by reverse phase.
By combining ionic and hydrophobic interactions, Promix MP is able to separate these analogs, differing in sequence by a single amino acid pair, using the slight differences in pI as illustrated below.
