CTSF, CATSF

≥ 0.9 pmole/min/µg.

Enzyme activity was measured in a buffer containing 100 mM Sodium acetate (pH 5.5), 2 mM EDTA, 8 mM DTT, 0.05% Brij, and 20 µM substrate (Z-FRAMC), with 3.75-30 ng/µl Cathepsin F. Reaction was done at 30°C for 40-120 min, and fluorescence signal was measured at Ex360 nm/Em460 nm. Enzyme was preactivated in 50 mM sodium acetate pH 4.5, 5 mM DTT buffer for 90 min at RT prior to reaction.

45 mM sodium acetate, 135 mM NaCl and 10% glycerol

Aqueous buffer solution

>6 months at -80°C.

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
