Waters Corp MassPREP Enolase Digest with Phosphopeptides Mix, Reversed Phase, UV, MS, Solid
The MassPREP™ Enolase Digest Phosphopeptide Mix is a complex sample mixture containing tryptically digested Yeast Enolase (SwissProt P00924) spiked with four Yeast Enolase derived phosphorylated peptides: T18p, T19p, T43p, T43pp. This sample is used to optimize phosphopeptide detection in LC/MS, LC/UV, and MALDI-MS analyses. It provides control over sample preparation, allowing use of pure peptides or defining the phosphopeptide to unmodified peptide ratio.
- Optimizes phosphopeptide detection in LC/MS, LC/UV, and MALDI-MS analyses.
- Provides control over sample preparation, allowing use of pure peptides or defining phosphopeptide to unmodified peptide ratio.
- Held to strict quality control criteria.
- Comes with test results for the purity of the mix.
- Contains tryptically digested yeast enolase spiked in four yeast enolase-derived phosphorylated peptides.
