Phorbol myristate acetate. NF-κB Activator

Phorbol 12-myristate 13-acetate (PMA), also known as 12-O-tetradecanoylphorbol 13-acetate (TPA), is a specific activator of Protein Kinase C (PKC) and hence activates nuclear factor-kappa B (NF-κB). NF-κB is a transcription factor that regulates numerous physiological functions and is involved in the pathogenesis of various diseases. It has been identified as a potential therapeutic target in inflammatory processes, cancer, and autoimmune diseases[1].

PMA is the most common and potent phorbol ester. It is active at nanomolar concentrations and activates NF-κB in a dose-dependent manner [1]. PMA causes a wide range of effects in cells and tissues and is a very potent mouse skin tumor promoter [2, 3].

InvivoGen’s PMA is designed to study the NF-κB pathway in cellular assays.


Key Features of PMA:

  • Potent activator of NF-κB in vitro
  • Each lot of PMA is highly pure (≥98%) and functionally tested

Evaluation of NF-kB activation with PMA
Evaluation of NF-kB activation with PMA

PMA  induces a dose-dependent response in HEK-Blue™ hTLR4 cells.
HEK-Blue™ hTLR4 cells were stimulated with increasing concentrations of PMA. After overnight incubation, the NF-κB response was determined using QUANTI-Blue™, a SEAP detection reagent, and by reading the optical density (OD) at 655 nm.
