Amphipol A8-35

(C6.2H10.3O1.35N0.65N0.35)~ 35 Mr ca. 8 kDa

Amphipathic surfactant for maintaining solubilized membrane proteins in detergent-free solutions.
Amphipols are a non-detergent alternative for stabilizing membrane proteins in aqueous solutions. Extracted membrane proteins can be exchanged into these amphipathic polymers, keeping them soluble in detergent-free, aqueous solution while stabilizing them biochemically.
Solubility: up to 20 % in water

Applications

  • Cryo- and electron microscopy
  • Stabilization of native membrane protein structure
  • In vitro functional studies
  • Facilitating membrane protein folding/refolding
  • NMR
  • Immobilization of membrane proteins onto solid surface
