Cyanine 5 PI(4 5)P2 C16 - 50 ug

Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol 4 5-bisphosphate (PIP2) has been shown to play a central role in a variety of cellular functions. Amongst its many functions PIP2 is a substrate for Phospholipase C-coupled G-protein pathways involved in intracellular calcium release in a number of tissues. It is also a substrate for class I phosphoinositide 3-kinase (PI3-K) forming PI(3 4 5)P3. This analog of PI(4 5)P2 is labeled with the red fluorophore Cyanine 5 (Cy5)
