General description
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 it is stable over a wide pH and temperature range. Has an optimal pH of 7.5. Note: 1 KU = 1000 units.
Note: 1 KU = 1000 units.
Physical form
Lyophilized from a solution containing calcium acetate as a stabilizer.
Preparation Note
