Description Application Adenosine 5′-phosphosulfate sodium salt has been used in enzyme-linked bioluminescence assay for adenosine triphosphate (ATP) and pyrophosphate quantification. Packaging 5 mg in glass bottle 50 mg in poly bottle Biochem/physiol Actions Adenosine 5′ phosphosulfate (APS) is used as a substrate of adenosine triphosphate (ATP) sulfurylase to complete a PP(i)-recycling loop for exponential ATP amplification in firefly luciferase ATP luminescence assay and other pyrophosphate regeneration-dependent detection assays.
