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).

TRITON X-100 IB07100 Non-ionic detergent used to denature cell membranes and to break up protein aggregates Triton X-100 is a non-ionic detergent used to denature cell membranes without denaturing the protein. Triton X-100 breaks up protein aggregates to promote enzymatic activity.
