Certificate of Analysis

  • LC Labs has been the primary worldwide supplier of PMA for laboratory research for more than 37 years
    • More than 250,000 vials of our PMA have been used by many thousands of labs since 1980
    • More than a dozen major biochemical reagent vendors sell our PMA under their own labels
    • Thus, any PMA you may have used during the past few decades was mostly likely manufactured by LC Labs
    • Our 1, 5, 10 and 25 mg sizes of PMA are now regularly supplied in crimp-top vials with teflon-lined septum seals for easy reconstitution and liquid handling. This new form of packaging replaces the flame-sealed snap-top vials that we used previously for those sizes.
    • The 100 mg size of PMA will continue to be supplied in flame-sealed snap-top vials under a nitrogen atmosphere for long-term stability (many years).
    • We continue to offer PMA in flame-sealed snap-top vials for all sizes. Please request "Flame-Sealed Vials" when placing your order.
  • This is the most commonly used phorbol ester. It binds to and activates protein kinase C, causes an extremely wide range of effects in cells and tissues, and is a very potent mouse skin tumor promoter. Blumberg, P.M. "In vitro studies on the mode of action of the phorbol esters, potent tumor promoters: part 1." Crit. Rev. Toxicol. 8: 153-197 (1980) and Blumberg, P.M. "In vitro studies on the mode of action of the phorbol esters, potent tumor promoters, part 2." Crit. Rev. Toxicol. 8: 199-234 (1980).
  • Although PMA is quite toxic, it has shown anti-leukemic and anti-neutropenic activity in humans. Han, Z.T. et al.
