Rapid, Automated Peptide Mapping for Multi Attribute Monitoring

SMART Digest kits for peptide mapping and peptide quantitation

  • Choose from trypsin, chymotrypsin, or proteinase K kits for sequence-specific cleavage of your protein.
  • Use SMART Digest ImmunoAffinity (IA) kits for immunoaffinity capture and trypsin digestion in a single well. The Immunoaffinity reagent (streptavidin, protein A, or protein G) captures the protein and increases sensitivity by purifying low level proteins from complex biological matrices. The trypsin enzyme is activated at elevated temperatures for accelerated digestion under protein denaturing conditions.
