Endoproteinase Lys-C 

Endoproteinase Lys-C is a protease that cleaves proteins on the C-terminal side of lysine residues and is commonly used for protein sequencing^[1].

This product can be used for: 1) protein sequence analysis; 2) synthesis of lysine-related derivatives.

Protocol
This product can be directly used for protein enzyme digestion. The recommended enzyme digestion ratio is 1:50-1:200, and the enzyme digestion should be performed at 37 ℃ overnight.

Notes
1) The optimal reaction pH of this product is 9.0-9.5, and the optimal reaction temperature is 30-37 ℃. It can still maintain high enzyme activity in the presence of 4 M urea or 0.1% SDS.
2) Buffer: 20 mM Tris-HCl, pH=8.0.
3) Do not freeze and thaw repeatedly.

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
