General description

Brain extract has lipids, especially polyunsaturated fatty acids (PUFAs) at high level. Extract from substantia niagra and the striatum has high amount of iron.[1]

Application

Brain Extract from bovine brain has been used:
  • to prepare small unilamellar vesicles[2]
  • in lipid binding assay[3]
  • to aid the recovery of phosphoinositides and also to terminate the reaction in phosphatidylinositol 5-phosphate (PtdIns5P) and PtdIns4P assay[4]
  • in liposome and protein self-aggregation assays[5]

Biochem/physiol Actions

Brain lipids are involved in cellular signal transduction, membrane organization, trafficking protein modification, interactions and energy storage.[6]

Packaging

Sealed ampule.

Components

Contains phosphatidylinositol phosphatidylserine,other brain lipids.
