Technical Data
DAPT (N-S-phenylglycine tert.butyl ester)
Biochemicals Storage: 4C/-20CShipping: Blue Ice
Cell permeable gamma-secretase inhibitor (IC50 = 115 nM for total beta-amyloid, IC50 = 200 nM for beta-amyloid 1-42). Reduces Abeta levels in vivo. Blocks the proteolytic processing of neurotrophin receptor alike death domain protein (NRADD). Does not inhibit persenilinase. Notch processing inhibitor. Enhances neuronal differentiation independent of sonic hedgehog (Shh) signaling. CDK5 activity inhibitor. Apoptosis enhancer.
