PROTEINASE K IB05400 CAS#: 39450-01-6

PROTEINASE K SOLUTION IB05406 Concentration: 20mg/ml Used for digestion of the protein keratin IBI’s Proteinase K Solution is a stable 20 mg/ml highly active proteolytic enzyme that is purified from the moldTritirachium album. The enzyme has two binding sites for Ca++, which lie some distance from the active site and are not directly involved in the catalytic mechanism. The high activity of the enzyme solution (0.6 U/µl) means that you can keep the reaction volumes low (as low as 200 µg/ml).

DITHIOTHREITOL (DTT) Used in enzyme preparation to stabilize the enzyme. DTT is used in enzyme preparations to prevent formation of disulfides from sulfhydryl groups. This stabilizes the enzyme. DTT should be warmed to room temperature before opening. DTT solutions should be made fresh prior to use. Do not autoclave DTT or solutions containing DTT.
