Lysyl Endopeptidase®, Mass Spectrometry Grade (Lys-C)

Lysyl Endopeptidase^®, Mass Spectrometry Grade (Lys-C) is a highly specific serine protease used in proteomics research, peptide mapping, and mass spectrometry sample preparation. Derived from Lysobacter enzymogenes, the enzyme selectively cleaves peptide bonds at the carboxy terminus of lysine residues, providing highly predictable protein digestion and peptide generation.
Its exceptional specificity makes Lys-C a valuable tool for peptide fragmentation and primary structure analysis of proteins. The enzyme is widely used in proteomics workflows where accurate and reproducible protein digestion is essential for downstream LC-MS/MS analysis, peptide identification, and protein characterization.

Manufactured to mass spectrometry grade standards, Lysyl Endopeptidase enables researchers to generate consistent peptide fragments that support high-confidence protein analysis. The lyophilized formulation is optimized for proteome research applications requiring reliable enzymatic digestion and analytical reproducibility.
