Product Usage Information

Dexamethasone is supplied as a lyophilized powder. For a 10 mM stock, reconstitute the 5 mg in 1.27 ml DMSO. Working concentrations and length of treatment can vary depending on the desired effect, but it is typically used at 10-1,000 nM for 1-24 hr.


Store lyophilized or in solution at -20ºC, desiccated. Protect from light. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

Dexamethasone is a synthetic glucocorticoid that binds to the human glucocorticoid receptor (GR). Treatment of cells with dexamethasone leads to nuclear translocation and activation of GR. This elicits anti-inflammatory, cellular proliferation, and metabolic responses via GR-mediated transcriptional activation or repression of target genes (1-4). Research studies show that dexamethasone inhibits dendritic cell differentiation and maturation (5). The inhibition of nitric oxide synthase by dexamethasone has also been observed (6).
