Human PARP9 (GenBank Accession No. NM_031458), full length with N-terminal GST tag, MW = 119 kDa, expressed in a Baculovirus infected Sf9 cell expression system.
Aplicación
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Definición de unidad
One unit of PARP incorporates 100 pmoles of poly(ADP) in 1 minute (room temperature) from NAD into acid-insoluble form.
Forma física
Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 50% glycerol and 3 mM DTT.
Nota de preparación
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.
