PtdIns-(4,5)-P2-fluorescein (PI(4,5)P2-fluorescein) triethylammonium is a fluorescently labeled phosphatidylinositol-4,5-bisphosphate, which is a marked form of an important phospholipid signaling molecule (PIP2) on the cell membrane. PtdIns-(4,5)-P2-fluorescein triethylammonium can be used to detect proteins that interact with phosphatidylinositol-4,5-bisphosphate, such as PI3K, PTEN, and PH domain proteins, etc [1].
