3′-磷酸腺苷5′-磷酸（PAP），为3′-磷酸化的核苷酸，几乎存在于所有生物中，是硫和脂质代谢的副产物。 用途 腺苷3′,5′-二磷酸二钠盐用于： 在二维薄层色谱中，在纤维素高效薄层色谱（HPTLC）板上点样 在酶活性试验中，研究 HOS2 / FIERY1野生型 hos2突变体和fiery1？2突变蛋白对3′-磷酸磷腺苷5′-磷酸（PAP）的活性 作为标准品，定量磷酸腺苷 3′-phosphoadenosine 5′-phosphate (PAP), a 3′-phosphorylated nucleotide is found in almost all organisms and is obtained as a by-product of sulfur and lipid metabolism. Purpose Adenosine 3′,5′-diphosphate disodium salt has been used: to spot sample on cellulose high-performance thin-layer chromatography (HPTLC) plates in two-dimensional thin layer chromatography in enzyme activity assay to study the activities of HOS2/FIERY1 wild type hos2 mutant and fiery1?2 mutant protein against 3′-phosphoadenosine 5′-phosphate (PAP) as a standard for the quantification of phosphoadenosines
