Biological Activity: 2-5A (2′,5′-ApApA) is a 5'-triphosphorylated (2',5') oligoadenylate. When covalently linked to an antisense molecule complementary to the target sequence, 2-5A activates RNase L, which subsequently degrades the target RNA bound to the 2-5A chimera. 2-5A can be used in research related to respiratory syncytial virus infection, colorectal adenocarcinoma and melanoma[1][2][3].
