Specifications

Trichostatin A is an antifungal antibiotic that is a reversible, potent and specific inhibitor of mammalian histone deacetylase (HDAC) both in vivo and in vitro. Histone deacetylase inhibition causes chromatin relaxation and gene expression modulation. May induce apoptosis. TSA inhibits the eukaryotic cell cycle and induces morphological reversion of transformed cells. It blocks cell cycle progression at G1 phase in Hela Cells. TSA causes accumulation of highly acetylated histones in vivo, while inhibiting the activity of partially purified histone deacetylase in vitro.
Catalog #T8375-05
ApplicationsSuitable for use in Inhibition of Histone Deacetylation. Other applications not tested.
Recommended DilutionInhibition of Histone Deacetylation: Incubation of A431 cells with 50-100ng/ml Trichostatin A for 24 hours inhibited deacetylation of histones in vivo, as detected using anti-acetylated Histone H4.
The optimal concentration of Trichostatin A should be empirically determined for the type of cells and assay used.
