摘要

The interferon induced enzyme 2′5′ oligoadenylate synthetase produces 2′5′ pppA(pA)n the first discovered natural nucleotide with a 2′5′ linkage. We describe a direct assay of this enzyme based on separation by thin layer chromatography (TLC) of the substrate ATP and the products 2′5′pppA(pA)n (n ≥ 1). This technique presents obvious advantages compared to the currently used methods. Moreover the enzyme uses other nucleotides as substrates forming co-oligonucleotides 2′5′pppA(pA)n pN (N= U,G,C,dA,dG,dT and dC). Additional procedures are described using different developing solvent systems for the separation of the core-2′5′ oligonucleotides (2′5 A(pA)npN) containing AMP-residues entirely and those with another nucleotide at the 2′end.
