General description

Human Sirtuin 1, GenBank Accession No. NM_012238), amino acids 193-741 with N-terminal ST tag, MW = 87.2 kDa, expressed in E. coli expression system.

Application

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

Unit Definition

One unit is defined as the amount of enzyme required to deacetylate 1 pmol of substrate/min at 37°C.

Physical form

Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20 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.

Nicotinic acid (NA) has recently been shown to inhibit inflammatory response in cardiovascular disease. Sirtuin1 (SIRT1), a NAD(+)-dependent class III histone deacetylase, participates in the regulation of cellular inflammation. We hypothesized that dietary supplementation of NA could attenuate vascular inflammation
