A relatively non-toxic Inhibitor of histone deacetylase (HDAC). Facilitates transcriptional activation (TGF-b/Smad4) in both stable and transient receptor assays in a concentration-dependent manner. At ~2ug/ml (6-8uM) concentrations, results in a greater than 100-fold increase in histone acetylation in PANC-1 cells.Formula:C18H18N2O4Solubility:DMSO (~100mM)Molecular Weight:~326.35Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store 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.
