Product Information

Product Usage Information

Application Dilution
Immunofluorescence (Immunocytochemistry) 1:800 - 1:3200

Storage

Supplied in a PBS solution that does not contain any stabilizers or preservatives and has been lyophilized. The lyophilized antibody is stable for 24 months when stored at -20°C. Reconstitute using 200 μl of sterile distilled water to create a 1 mg/ml solution. A slight precipitate may be present, but will not interfere with antibody performance. Recommended to centrifuge the reconstituted antibody and use the supernatant. Once reconstituted, this product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles.

Specificity / Sensitivity

dsRNA (K1) Mouse mAb recognizes dsRNA where the length of the helix is greater than or equal to 40 base pairs (bp). The ability to recognize dsRNA is independent of the sequence and nucleotide composition of the antigen. The K1 clone shows a higher affinity to poly(I:C) than to other dsRNA antigens (6).

Species Reactivity:

All Species Expected

Source / Purification

Monoclonal antibody is produced by immunizing animals with a nucleic acid sequence.

Background

Double-stranded RNA (dsRNA) is produced during the replication cycle of a broad range of viruses and can trigger the innate immune response. dsRNA is present if cells are infected with a dsRNA virus or it can be generated during the course of single-stranded RNA (ssRNA) virus replication. Host cells do not produce dsRNA so the innate immune response can differentiate between host and viral RNAs by the presence of dsRNA (1). The innate immune response is controlled by several classes of germline-encoded pattern-recognition receptors (PRRs), including retinoic acid-inducible gene-I (RIG-I)-like receptors (RLRs), Toll-like receptors (TLRs), and NOD-like receptors (NLRs) that sense viral components, such as dsRNA, ssRNA, and DNA (2,3). Activation of PRRs by dsRNA leads to production of type I interferons (IFNs) and proinflammatory cytokines, triggering the adaptive immune response (2,3). Understanding how antiviral responses are initiated, the counter strategies that viruses adopt, and exploring the viral life cycle gives researchers a better comprehension of how to treat infections of different viral diseases (4,5).
