Additional Information

Product Data
Synonyms Polyinosinic-polycytidylic acid, potassium salt (poly (I:C))
Properties
MW High molecular weight (>1.5kb).
CAS 31852-29-6
Purity ≥99%
Reconstitution Just before use, prepare a stock solution in endotoxin-free and sterile ddWater (Cat. No.: IAX-900-002), or PBS (Cat. No.: IAX-900-001).
Formulation Lyophilized. Sterile.
Biological Activity Activates TLR3, MDA5/Helicard and RIG-I. Optimal working concentration depends upon target receptor accessibility, number, density, as well as cell type, and therefore needs to be determined for each application. Recommended concentration range: in vitro: 0.5-10μg/ml; in vivo: 5mg/kg.
Endotoxin Content <0.002EU/μg
Origin Manufactured by Innaxon.
Other Product Data Contains: 2mg and 5mg sizes include 1.5ml ddWater Endotoxin-free (sterile) (Cat. No.: IAX-900-002-LD15). 10mg size includes 10ml ddWater Endotoxin-free (sterile) (Cat. No.: IAX-900-002-L010). 
Reconstitution Note: For optimal dissolving, add 50% of solvent and let dissolve for 10min. Add remaining 50% of the solvent and mix thoroughly. Moderate warming may aid dissolving.

Product Description

Toll-like receptor (TLR) 3 is an endosomal TLR that mediates immune responses against viral infections upon activation by its ligand double-stranded RNA, a replication intermediate of most viruses. TLR3 is expressed widely in the body and activates both the innate and adaptive immune systems. Toll-like receptor 3 (TLR3), melanoma differentiation-associated gene 5 (MDA5), and retinoic acid-inducible gene-I (RIG-I), all sensors of double-stranded RNA (dsRNA) are potent inducers of antiviral activity. dsRNA sensor activation -e.g. by poly (I:C)- induces pro-inflammatory TNF-α and antiviral IFN-β, but can also enhance the expression of pro-apoptotic proteins. Recently, poly (I:C)-induced cell death recently gained considerable attention as a tool to study the 'Ripoptosome' or 'Necrosome' complex, a novel intracellular signaling complex, thought to induce regulated necrosis, also called 'Necroptosis'.
