Description_x000D_ Application_x000D_ UTP has been used as a P2 receptor activator to study its effects on proton efflux in MC3T3-E1 and UMR-106 cells. UTP has also been studied in combination with amiloride hydrochloride in nebulizer solutions for treating cystic fibrosis._x000D_ Uridine 5′-triphosphate has been used in a study to show that fluoxetine (FLX), mediates its anti-depressive effect by increasing the gliotransmission of adenosine 5′-triphosphate (ATP)._x000D_ Biochem/physiol Actions_x000D_ Uridine-5′-Triphosphate (UTP) is a cytosolic nucleotide component of nucleic acids. It serves as a signaling molecule in the extracellular space. Uridine-5′-Triphosphate (UTP) is involved in various pathophysiological responses in the nervous system. UTP also plays a major role in the regeneration process._x000D_ P2Y receptor agonist._x000D_ Packaging_x000D_ Bottomless glass bottle. Contents are inside inserted fused cone._x000D_ Preparation Note_x000D_ 25 mg of Uridine 5′-triphosphate trisodium salt (UTP Na3) hydrate is soluble in 0.5 ml of water and yields a clear, colorless solution.
