Divalproex sodium increases the level of acetylated histone H3 level in ataxin-3-transfected HEK293 cells. Normal (15CAG) or expanded (77CAG) ataxin-3-transfected cells were treated with divalproex sodium (Selleck chemical, 0.3 mmol/L in DMSO, (+)) or with DMSO alone (−) 48 h after transfection. The cells were treated with divalproex sodium or DMSO over 6, 12, and 24 h. The Western blot was probed with antiacetylated histone H3, antihistone H3, and antiataxin-3. Antibodies include antihistone H3 and antiataxin-3 are used as controls. The x-axis shows the different treatment group. The y-axis represents the acetylated histone H3 values normalized to histone H3. Error bars represent the standard error of the mean. Data represent three independent experiments (n = 3). The data with a normal distribution were analyzed with Student’s t-test. *P < 0.05

Divalproex sodium enhances IM-induced cell growth inhibition, apoptosis and cell cycle arrest in K562-S and K562-G cells. Divalproex sodium enhances the inhibitory effects of IM on SIRT1 expression in K562-S and K562-G cells. Divalproex sodium enhances the effect of IM on apoptosis in K562-G cells partly through SIRT1.  Divalproex (500 mg/kg) significantly increases dopamine (DA) and acetylcholine (ACh) efflux in the rat hippocampus, and DA, but not ACh, efflux in the rat medial prefrontal cortex (mPFC), whereas a lower dose of Divalproex, 50 mg/kg, has no effect on DA or ACh in either region. Divalproex (50 mg/kg) combined with the atypical APDs Olanzapine (1.0 mg/kg) or Aripiprazole (0.3 mg/kg) significantly potentiates the effect of both antipsychotic drugs (APDs) on DA, but not ACh efflux in the HIP and mPFC.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
