Biological Activity

Tyloxapol (Triton WR1339) is a nonionic alkyl aryl polyether alcohol surfactant that inhibits plasma lipolytic activity and lipoprotein lipase. By blocking the breakdown of triglyceride-rich lipoproteins, Tyloxapol disrupts lipid clearance, leading to elevated serum triglyceride and cholesterol levels. Additionally, Tyloxapol suppresses NF-kB signaling and reduces proinflammatory cytokine production, supporting its utility in establishing animal models of hyperlipidemia and atherosclerosis. [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).
