Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Definicja jednostki
Jedna jednostka PARP włącza 100 pmoli poli(ADP) w ciągu 1 minuty (temperatura pokojowa) z NAD do postaci nierozpuszczalnej w kwasie.
Postać fizyczna
Formuła w 25 mM Tris-HCl, pH 8,0, 100 mM NaCl, 0,05% Tween-20, 20% glicerolu i 3 mM DTT.
Uwaga dotycząca przygotowania
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.

Nicotinamide adenine dinucleotide (NAD+)-dependent ADP-ribosylation plays important roles in physiology and pathophysiology. It has been challenging to study this key type of enzymatic post-translational modification in particular for protein poly-ADP-ribosylation (PARylation). Here we explore chemical and chemoenzymatic synthesis of NAD+
Inhibition of Poly(ADP-ribose) Polymerase1 (PARP1) impairs DNA damage repair, and early generation PARP1/2 inhibitors (olaparib, niraparib, etc.) have demonstrated clinical proof of concept for cancer treatment. Here, we describe the development of the novel PARP inhibitor E7449, a potent PARP1/2
