Selective Enrichment and Fractionation of Phosphopeptides from Peptide Mixtures by Isoelectric Focusing after Methyl Esterification

We have developed a new strategy to enrich and fractionate phosphopeptides from peptide mixtures based on difference in their isoelectric points (pIs) after methyl esterification. After isoelectric focusing (IEF) of a methylated tryptic digest of a mixture of α-S-casein and β-casein, phosphopeptides...
