PDBu is supplied as a lyophilized powder. For a 2 mM stock, reconstitute the 1 mg in 990.9 µl DMSO. Working concentrations and length of treatment can vary depending on the desired effect, but it is typically used at 20-2000 nM for 15-30 min. Soluble in DMSO or ethanol.Storage: Store lyophilized or in solution at -20ºC, desiccated. 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.
Phorbol 12, 13-Dibutyrate (PDBu) is a phorbol ester and a potent activator of protein kinase C (PKC). Frequently used in cancer research, PDBu is widely characterized to promote tumors in a variety of tissue types (1,2). PDBu treatment of cells can lead to activation of downstream PKC targets such as p44/42 MAPK and MARCKS (3-5). Although less potent than TPA, research has shown PDBu elicits less nonspecific binding (6,7) and is less hydrophobic allowing for easy wash out from cells in tissue culture (8).
