General description

Cathepsin K is a member of the papain superfamily of cysteine proteinases and plays an important role in osteoclast-mediated bone resorption and collagen degradation. It is primarily expressed by osteoclasts and recent studies also suggest its expression in fibroblasts. Irregularities in cathepsin K activity, either too high or too low, contribute to osteopenic disorders such as osteoporosis and pycnodysostosis. This recombinant enzyme contains a C-terminal His•Tag sequence.
Note: 1 mU = 1 milliunit.

Packaging

Please refer to vial label for lot-specific concentration.

Physical form

In 50 mM NaOAC, pH 5.5. The activation was stopped by addition of 10 mM MMTS, which can be removed under reducing conditions.

Preparation Note

Following initial thaw, aliquot and freeze (-70°C).
