Technical Data
SIRT1, phosphorylated (Ser47) (SIRT1 Sir2-like Proteins (Sirtuins) Type 1, Sirtuin, Sirtuin (Silent Mating Type Information Regulation 2 Homolog) 1 (S. cerevisiae), Sirtuin Type 1, BA57G10.4, hSIRT1, NAD-dependent Deacetylase SIRT1, NAD-dependent Deacety
The S. cerevisiae silent information regulator 2 (Sir2) protein is an NAD+-dependent histone deacetylase (HDACs) that plays a critical role in transcriptional silencing, genome stability, and longevity (1-2). Part of the Sirtuin family (Sir2, Sir3, Sir3), yeast Sir2 is the founding member of Class III HDACs. A human homologue of Sir2, SIRT1, regulates the activity of the p53 tumor suppressor and inhibits apoptosis (3-4).

Suitable for use in Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000-1:2000
Immunohistochemistry: 1:250-1:500
Immunocytochemistry: 1:100-1:250
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
