MagReSyn® Chymotrypsin

For rapid, automated chymotryptic digestion of proteins for mass spectrometry sample preparation

MagReSyn® Chymotrypsin microparticles consist of covalently immobilized sequencing grade chymotrypsin (TLCK treated to prevent tryptic activity) for protein digestion prior to mass spectrometry analysis. The porous high capacity MagReSyn® microparticle technology allows for high volumetric enzyme activity allowing for rapid digestion. The magnetically immobilized chymotrypsin enables automated and miniaturized digestion workflows improving reproducibility. The enzyme cleaves at bulky hydrophobic residues thus providing complementary protein coverage as compared to magnetically immobilized trypsin digestion (see MagReSyn® Trypsin). Product is made to order, please contact us for ordering.

Product Resources

MagReSyn® Chymotrypsin Performance Superiority

Rapid protocols

  • High Chymotrypsin content ensures rapid digestion

Improved stability and compatibility

  • Multipoint covalent attachment of chymotrypsin
  • Low chymotrypsin leaching reduces sample contamination
  • Increased sequence coverage – complementary to chymotrypsin cleavage


  • Suitable for automated digestion on magnetic handling stations
  • Reduce sample preparation variability and improves reproducibility

Digestion with MagReSyn® Chymotrypsin provides good protein coverage for a range of proteins,
including large and difficult to digest examples such as Thyroglobulin and Myoglobin.
