General description

["TWEEN"] 80 is a polyethylene sorbitol ester, broadly used in biochemical applications like solubilizing proteins, isolating nuclei from cells in culture, and growing tubercle bacilli. It is also useful in emulsifying and dispersing substances in medicinal and food products. TWEEN 80 acts as an active drying agent in ice cream.

Application

["TWEEN"] 80 has been used:
  • to dissolve rapamycin (RAPA) for immunosuppressive treatment to perform in vivo studies in mice
  • to dissolve remodelin and remodelin Fluor to assess remodelin toxicity in vivo and small molecule dosing
  • to prepare assay medium for the microbiological assay for total folate
