OA Lys-C, MS Grade
Sequencing-grade Endoproteinase Lys-C, quality-controlled and lyophilized for LC-MS proteomics workflows.
Reliable C-Terminal Lysine Cleavage
OA Lys-C is sequencing-grade Endoproteinase Lys-C prepared for mass spectrometry. It cleaves specifically at the C-terminal side of lysine residues, remains active under denaturing conditions, and pairs with trypsin or Lys-N for expanded proteome coverage. Lyophilized from LC-MS-compatible buffer — no clean-up required. Certificate of Analysis with every lot.

Applications
Denaturing Digestion Workflows
Maintains activity under denaturing conditions to support efficient cleavage of complex proteins before LC-MS analysis.
Sequential Digestion
Pair with trypsin for improved digestion completeness or with Lys-N for complementary lysine-directed peptide sets.
Expanded Proteome Coverage
Use C-terminal lysine specificity as an orthogonal digestion strategy for deeper protein characterization.
