|Description||Dehydroepiandrosterone is an important endogenous steroid hormone, which is an androgen receptor antagonist and an estrogen receptor agonist.|
Dehydroepiandrosterone (10-100 nM for 6-8 hours) protects primary hippocampal cultures from embryonic day 18 (E18) embryos against NMDA-induced toxicity (0.1, 1, 10, and 50 mM). Dehydroepiandrosterone also reduces NMDA-induced toxicity (1 mM), although the lowest effective dose of DHEAS (100 nM) is higher than that of Dehydroepiandrosterone (10 nM). Dehydroepiandrosterone (100 nM) protects cultured neurons against the neurotoxic actions of either AMPA (25 mM) or kainic acid (1 mM) as well.  Dehydroepiandrosterone produces much greater levels of IL 2 than normals in response to stimulation. Dehydroepiandrosterone causes an enhanced capacity to secrete IL 2 following activation. Dehydroepiandrosterone augmentes IL 2 production by activated cloned T cell line.  Dehydroepiandrosterone increases the length of neurites containing the axonal marker Tau-1, and the incidence of varicosities and basket-like process formations in a dose-dependent fashion in primary cultures of mouse embryonic neocortical neurons. Dehydroepiandrosterone rapidly increases free intracellular calcium via activation of N-methyl-D-aspartate (NMDA) receptors. Dehydroepiandrosterone regulates the motility and/or growth of neocortical neurons. 
|In vivo||Dehydroepiandrosterone, which results in plasma levels that resembled those in young adult humans, protects hippocampal CA1/2 neurons against unilateral infusions of 5 or 10 nmol of NMDA. |

|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
For best results, use promptly after mixing.
* 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 (g) = Concentration (mol/L) × Volume (L) × 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.
