Modified Lysine-C 3 x 5 µg

substance packed in 3 individually sealed vials

Highly purified modified Lysine with extremely low autolysis and therefore greater control of protein fragmentation. Consistent Enzyme activity over long digestion periods. Characteristics: Lysine-C endopeptidase from Lysobacter enzymogenes is a serine protease with high specificity for the cleavage of peptide bonds on the carboxy side of Lysine. Chemical Modification: Highly purified enzyme is modified chemically by a process developed at Princeton Separations. As a result, the modified enzyme is made highly resistant to autolysis and has improved stability. The modified enzyme retains at least 90% of its activity after 6 hours incubation at 30°C in reaction buffer and at least 65% of its activity after 24 hour incubation under the same conditions, with retention of specificity for Lysine.
