Application

Active human cathepsin V is useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Active human cathepsin V has been used in a study to assess the cysteine protease attribute of the eukaryotic ribosomal protein S4. Active human cathepsin V has also been used in a study to determine that the simultaneous treatment of human bronchial epithelial cells with serine and cysteine protease inhibitors prevents severe acute respiratory syndrome coronavirus entry.

General description

Physical form

Formulated in 40 mM MES, pH 5.0, 120 mM NaCL and 20% glycerol.

Preparation Note

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.

Unit Definition

One unit is defined as the amount of enzyme that will cleave 1 pmol of substrate per min at 37°C
