Merck, A1651-25MG, Adenosine 3′-phosphate 5′-phosphosulfate lithium salt hydrate

Application
3′-Phosphoadenosine 5′-phosphosulfate (PAPS) is used as a universal sulfonate donor for in vivo sulfonation by sulfotransferases. PAPS is used for the sulfation of glycans. PAPS is also useful to study the distribution and function of its biological transporter(s).
Adenosine 3′-phosphate 5′-phosphosulfate lithium salt has been used in a study that cloned and characterized a mammalian lithium-sensitive bisphosphate 3′-nucleotidase inhibited by inositol 1,4-bisphosphate. Adenosine 3′-phosphate 5′-phosphosulfate lithium salt has also been used in a study to assess the golgi-resident PAP-specific 3′-phosphatase-coupled sulfotransferase assays.
Analysis Note
Major impurities appear to be adenosine 3′,5′-diphosphate, sulfate and ammonia substitution products.
Disclaimer
Rapid decomposition occurs when exposed to room temperature: up to 17% per day at 37 °C. We ship on dry ice to minimize decomposition in transit.
