MassPREP Phosphopeptide Sample Kit - Enolase

The MassPREP&trade, Phosphopeptide Kit contains one piece of 186002325 MassPREP&trade, Enolase Digest and one piece of 186003285 MassPREP&trade, Phosphopeptide Standard Enolase which contains 4 Yeast Enolase derived phosphorylated peptides, T18p, T19p, T43p, T43pp. This kit allows maximum flexibility for mixing a complex sample spiked with a known mixture of phospotylated peptides to help optimize phosphopeptide detection in LC/MS, LC/UV and MALDI-MS analyses. Using this standard, scientists have greater control over sample preparation, with the option to use pure peptides or to define phosphopeptide to unmodified peptide ratio.
