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

2-5A (1 μM; 4 h) TEA is imported by human HEK293T cells and BJ1 fibroblasts to activate RNase L-dependent IFN/ISG induction, while mouse MEFs, MC38 cells, BMDMs, human A549 cells, and THP-1 monocytes do not exhibit robust 2-5A TEA import activity[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Result:Stimulated significant IFNB1 and CXCL10 mRNA expression in human HEK293T cells and BJ1 fibroblasts.
Abolished IFN/ISG response in RNase L-knockout HEK293T and BJ1 cells.
Failed to induce robust IFN/ISG response in mouse MEFs, MC38 cells, BMDMs, human A549 cells, and THP-1 monocytes.
Induced robust IFN/ISG expression in all tested cell lines when transfected with Lipofectamine.
2-5A (10 μg; peritumoral injection; once daily; 3 consecutive days) TEA complexed with lipofectamine significantly inhibits B16 melanoma tumor growth in wild-type C57BL/6J mice[3].
2-5A (10 μg; peritumoral injection; once daily; 3 consecutive days) TEA complexed with lipofectamine significantly inhibits sgRnasel MC38 colorectal carcinoma tumor growth in wild-type C57BL/6J mice[3].
2-5A (10 μg; peritumoral injection; once daily; 3 consecutive days) TEA complexed with lipofectamine does not inhibit MC38 colorectal carcinoma tumor growth in RnaseI−/− mice[3].

Animal Model:C57BL/6J wild-type (6-8 weeks old, same sex, subcutaneous implantation of 5×105 WT MC38 cells)[3]
-
Dosage:10 μg (complexed with lipofectamine)

Result:Significantly inhibited MC38 tumor growth compared to PBS, naked 2-5A (TEA), or lipofectamine alone.
Showed statistically significant difference in tumor volume between the lipofectamine+2-5A group and lipofectamine alone group (P=0.0142).
