Lyophilized. Lyophilized from a solution containing calcium acetate as a stabilizer. HYGROSCOPIC. A non-specific protease liquefies mucins and digests proteins to free amino acids. Can be used to isolate living chondrocytes. Most active at neutral pH, but stable over wide range of pH and temperature. Note: 1KU = 1000 units. Activity: ≥45,000 proteolytic units/g dry weight. One unit is defined as the amount of enzyme that will liberate a digestion product equivalent to 25 µg of tyrosine per min at 40°C, pH 7.5. pH optimum 7.5. RTECS UK9595000, CAS 9036-06-0. Note: 1 KU = 1000 units.
