Splitomicin (Splitomycin, 1,2-Dihydro-3H-naphthopyran-3-one, 1-Naphthalen propanoic acid)
1mg
Biochemicals Storage: 4C/-20CShipping: Blue Ice
Potent cell permeable and selective inhibitor of yeast NAD+-dependent histone deacetylase (HDAC) Sir2p. Displays higher activity in vivo than in vitro. Sensitizes mammalian cells to a variety of DNA-damaging agents by abrogating Sir2p activity on p53. Acts by either altering or blocking access to the acetylated histone binding pocket. Shown to have diverse effects also in mammalian cells.

Storage and Stability:
Short-term Storage: +4C
Long-term Storage: -20C
Stable for at least 2 years after receipt when stored at -20C.
