Biological Activity

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer biomedical material that regulates cellular adhesion and immune cell responses without classical enzymatic targets. Surface topography of PTFE modulates macrophage adhesion and activation, influencing foreign body giant cell formation and inflammatory cytokine production, including TNF-α and IL-6. Furthermore, expanded PTFE implants elicit host immune activation marked by elevated TNF-α and IL-1α expression, directing local tissue infiltration and cellular responses. [1]

Solubility

All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO Insoluble
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO.)
Water Insoluble
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).
