Modified Proteinases

Modified Proteinases

Princeton Separations Sequencing Grade endopeptidases are highly purified enzymes that are modified chemically to reduce autolysis and increase enzyme stability. Use of modified enzymes results in greater control of protein fragmentation reactions due to consistent enzyme activity over long digestion periods.
