PTMs can be experimentally detected by a variety of techniques, including mass spectrometry, which can be challenging. PTM Reference Peptide Standards help to overcome challenges such as low endogenous abundance, low ionization intensity, changed fragmentation. JPT’s ready-to-use peptide collections, peptide pools and individual peptides carry 24 different post-translational modifications. Peptide sequences were carefully selected and defined for usage as reference standards in mass-spectrometry based proteomics to support PTM proteomics.
- Large range of PTM reference peptides
- Selected for high recovery in LC-MS
- Stable-isotope labeled (SIL)
- Purified (& absolutely quantified)
