Outline of Final Research Achievements

We have developed quick-freezing and freeze-fracture replica labeling (QF-FRL) method to analyze lipid distribution at the nano-meter level. The analysis of lipid distribution was limited to the lipids in the plasma membrane of the cell at first. In this study, we have further developed the QF-FRL method to analyze lipids in the membrane of various organelles at the inside of yeast and mammalian cells. And now we can establish the technique to specifically label phosphatidyl inositol 4-phosphat (PtdIns4P) by using anti-PtdIns4P antibody in the plasma membrane and the membrane of various organelle of inside cell. Now we examine the distribution of PtdIns4P at the nano-scale level.
