Opis

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

Following reconstitution, store in the refrigerator (4°C). Stock solutions are stable for 24 h at 4°C.

Other Notes

Narahashi, Y., et al. 1968. J. Biochem. 64, 427.

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.
