BODIPY TMR Phosphatidylinositol is a water soluble analog of Phosphatidylinositol (PI) labeled with the orange fluorophore, Bodipy®-TMR, at the sn-1 position.
Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol (PI or PtdIns) is biosynthesized from CDP-diacylglycerol and inositol by phosphatidylinositol synthase. PI is the building block for phosphoinositide polyphosphates through phosphorylation by PI-kinases and is a substrate for PI-PLC yielding diacylgelycerol.
