WebGrade. Proteolysis with Trypsin/Lys-C Mix, Mass Spec Grade, is speciﬁ c and generates tryptic peptides (i.e., peptides with C-terminal arginine and lysine residues). Trypsin/Lys-C Mix, Mass Spec Grade, addresses several known limitations to trypsin digestion. Typical trypsin reactions do not digest proteins to completion, missing 15–30% of Webreconstituted trypsin/Lys-C stock solutions at -20°C or -80°C in single-use volumes for longer-term stability. Minimize the number of stock solution freeze/thaw cycles by aliquoting stock solutions of enzyme mix. • Maximal trypsin/Lys-C activity occurs at pH 7-9; the protease mix is reversibly inactivated at pH < 4. Common digestion buffers ...
