Purification of small peptides labeled with Bolton-Hunter reagent.

ABSTRACT

A method utilizing high-voltage electrophoresis on paper is described whereby a pentapeptide (Asp-Ser-Asp-Pro-Arg) labeled with Bolton-Hunter reagent is separated from hydrolyzed reagent and unreacted peptide and is recovered from the electrophoretogram in high yield. The general applicability to other peptides is discussed.
