Endoproteinase Lys-C is a sequencing grade serine protease isolated from Lysobacter enzymogenes as a highly purified protease that hydrolyzes specifically at the carboxyl side of Lys. Lys-C activity is optimal in the pH range of 7.0–9.0. This sequencing grade enzyme can be used alone or in combination with other proteases to produce protein digests for peptide mapping applications or protein identification by peptide mass fingerprinting or MS/MS spectral matching. It is suitable for digestion reactions in-solution or in-gel.
