MALDI-MS Calibrants

This is a peptide standard for matrix-assisted laser desorption ionization (MALDI) mass spectrometry, which is widely used for the analysis of proteins and other biomolecules. It is highly purified and passes practical tests using MALDI-MS. Molecular weights in increments of 500 allow selection of a calibrant suitable for your sample.


  • High purity
  • Molecular weights in increments of 500 allow selection of a calibrant suitable for your sample
  • Divided into small volumes for low cost and ease of use

Quality assurance

Passes practical tests using MALDI-TOFMS
