General description

PMA (Phorbol 12-myristate 13-acetate) is an activator of protein kinase C (PKC) and a known tumor promoting agent. PMA also exhibits clastogenic (chromosome-breaking) activity.

Phorbol 12-myristate 13-acetate (PMA) can induce the activity of PLD1 (phospholipase D1) but not PLD2 (phospholipase D2).

Through the protein kinase C (PKC) signaling pathway, PMA is a tumor promoter associated with:

• gene transcription
• cell growth
• cell differentiation
• programmed cell death
• immune pathway
• receptor desensitization

Phorbol 12-myristate 13-acetate is used to study:

• growth factors
• hormones
• cytokines-mediated regulation of cellular growth and differentiation


PMA has been used:
• for the detection of intracellular cytokines
• in CellROX oxidative stress assay
• for Huh7 cell stimulation to investigate dipeptidyl peptidase 9 (DPP9) re-distribution
• as a positive control in B-cell receptor (BCR) stimulation of chronic lymphocytic leukaemia (CLL) cells
• in the differentiation of monocytes (THP -1) into macrophages

Suitable for
• molecular biology studies as standard
• analytical studies of tumor promoters
• promotion of cell growth
