Examples

Figure 7. The results showed that J2 antibody (GenScript, A02181), J2 antibody [Biotin] (GenScript, A02356) and J2 antibody [HRP] (GenScript, A02357) can be used for dsRNA Dot Blot assay development.

Background

Target Background	Double-stranded RNA (dsRNA) forms in nucleic acid strands containing complementary sequences. In gene therapy, minimization and removal of double-stranded RNA (dsRNA) is important for mRNA in vitro transcription (IVT) processes. Anti-dsRNA monoclonal antibody J2 is a useful tool in dsRNA detection. J2 antibody also can be used to detect dsRNA intermediates of Hepatitis C virus, Dengue virus, rhinovirus and Chikungunya virus. Since it was first published in 1991, J2 antibody has been broadly widely used to detect viral dsRNA in animals and plants in more than 200 scientific publications. The original J2 antibody was prepared by immunization of mice with L-dsRNA. GenScript Double-stranded RNA (dsRNA) Antibody (J2), mAb, Mouse is recombinant mouse monoclonal antibody, purified from cell culture free from animal-derived components.
