Lysine-specific Protein Digestion
LysCERATOR (Lys-C) is a lysine-specific endopeptidase that digests proteins C-terminally of lysine residues, including at lysine-proline linkages.
LysCERATOR is recombinantly produced to high purity and is ideally suited for mass spectrometry-based proteomics applications. Additionally, the enzyme supports peptide mapping, de novo sequencing and characterization of post-translational modifications.
- Best-in-class digestion efficiency at lysine residues minimizes missed cleavages
- Superior digestion at lysine-proline linkages
- Retains high activity under strong denaturing conditions
LysCERATOR™ Lyophilized
Lyophilized enzyme for lysine-specific protein digestionAbout LysCERATOR™

LysCERATOR (Lys-C) is a recombinantly produced lysyl endopeptidase that specifically digests peptide bonds C-terminally to lysine residues, including at lysine-proline linkages.
LysCERATOR is a highly efficient enzyme and ensures consistent and specific peptide cleavage whilst minimizing missed cleavages. By generating longer peptides than trypsin, LysCERATOR provides a complementary approach for peptide mapping experiments and can help improve overall sequence coverage. The enzyme is active in a pH range of 7.0 – 9.0 and retains high activity under denaturing conditions up to 8 M urea and 2 M guanidine hydrochloride.
