Ordering Information

Biological Activity

Mefenamic Acid is a nonsteroidal anti-inflammatory compound that acts as a competitive inhibitor of cyclooxygenase-1 (COX-1) and COX-2. By blocking COX activity, Mefenamic Acid prevents the conversion of arachidonic acid into prostaglandins such as PGE2, thereby downregulating inflammatory signaling pathways. This inhibition reduces downstream pro-inflammatory mediator production and modulates cellular responses associated with inflammation and cell proliferation. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
