Clone 2E9 recognizes an epitope on human/hamster/primate RNaseL.

RNase L is highly expressed in the spleen and thymus, followed by prostate, testis, uterus, small intestine, colon, and peripheral blood leukocytes.

RNase L antibody, clone 2E9, recognizes the interferon (IFN)-inducible 2-5A-dependent ribonuclease L (RNase L), an endoribonuclease involved in antiviral signaling. It is widely expressed as a latent monomer in most mammalian tissues¹. 2’,5’-oligoadenylate synthetase (OAS) is expressed following viral infection and exposure to IFN2. OAS proteins are activated by dsRNA, resulting in the production of 2’,5’-linked oligoadenylates (2-5A), which bind to latent RNase L, inducing dimerization and activation2. RNase L inhibits viral replication by cleaving viral and ribosomal RNA^3,4 and inducing apoptosis in virus-infected cells^5,6. RNase L is suggested to have antitumor effects, possibly through its pro-apoptotic activity⁷, and mutations in the RNASEL gene are associated with prostate cancer risk and progression^8,9.
