5-Acetylsalicylic acid is a nonsteroidal anti-inflammatory drug and salicylic acid derivative that targets cyclooxygenase signaling pathways. As a synthetic analog of salicylic acid, it acts to modulate inflammatory responses by reducing prostaglandin production. Inhibition of prostaglandin synthesis leads to downstream suppression of inflammatory mediator release, attenuated vascular permeability, and reduced cellular inflammatory responses. [1]

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).
