Product does not compete with ATP.

Primary TargetNa⁺,K⁺- ATPase

General description

Strong irritant for mouse skin, but only moderately active as a tumor promoter. Activates protein kinase C. Stimulates the phosphorylation of Na⁺,K⁺- ATPase, thereby inhibiting its activity. Promotes the expression of inducible NOS in cultured hepatocytes. Commonly used in binding studies or in applications requiring high concentrations of phorbol compounds.

Strong irritant for mouse skin, but only moderately active as a tumor promoter. Activates protein kinase C (PKC). Stimulates the phosphorylation of Na⁺-K⁺ ATPase, thereby inhibiting its activity. Promotes the expression of iNOS in cultured hepatocytes. PDBu can be diluted to 30 µM in aqueous solutions, so it is commonly used in binding studies or in applications requiring high concentrations. It is easier to remove PDBu than PMA from cells in culture.

Preparation Note

Further dilute with aqueous buffers just prior to use.

Reconstitution

Following reconstitution, aliquot and freeze (-20°C). DMSO stock solutions are stable for up to 6 months at -20°C. With frequent use, the DMSO stock solutions may accumulate water. The presence of water in the stock solution will accelerate the decomposition of the product, resulting in significant loss of activity in 2-3 months.

Warning

Toxicity: Highly Toxic & Carcinogenic / Teratogenic (I)
