| Outline of Final Research Achievements |
In a biomembrane, there are heterogeneous lipid composition like lipid raft. These heterogeneity supports many proteins' functions. Despite the importance of this heterogeneity, there are no direct method to detect these lipid heterogeneity. In this research, we have used antibody labeled nanoparticles and mass spectrometry to develop a new method that analyze the lipids surrounding the antigen proteins. As the results, we detected fatty acids which composing phospholipids which surrounds the antigen proteins by using gold nanoparticle, antibody and antigen complex linked covalently each other.
