Proteases and Protein-Cleaving Reagents

We offer purified and agarose-immobilized proteases for enzymatic proteolysis (cleavage or digestion) of proteins to facilitate amino acid sequencing, peptide analysis, and polypeptide structural characterization.

For protein digestion using mass spectrometry, we offer a wide range of highly purified and MS-validated proteases.
