Polyinosinic-polycytidylic acid sodium (Poly(I:C) sodium) is an analog of double-stranded RNA and an agonist of toll-like receptor 3 (TLR3) and retinoic acid inducible gene I (RIG-I)-like receptors with the potential to be used as a vaccine adjuvant to enhance innate and adaptive immune responses, and to alter the tumor microenvironment. It can directly trigger cancer cells to undergo apoptosis.
ln Vitro |
Polyinosinic-polycytidylic acid (20 ng/mL; 24 hours; WM793, WM278, WM239A, WM9, and 1205Lu cells) treatment dramatically decreased cell viability in a day, going from 100% of control to 20%–50%. %[1]. Treatment of 1205Lu cells with 200 ng/mL of polyinosinic-polycytidylic acid for 24 hours causes apoptosis in these cells.[1]. Melanoma cells treated with polyinosinic-polycytidylic acid (3 ng/mL; 24 hours; 1205Lu cells) express IFN-β. The stimulation of IFN-β by polyinosinic-polycytidylic acid requires IPS-1 and RIG-I and MDA-5, respectively, as demonstrated by the silencing of these two proteins [1].
In melanoma cells, treatment with polyinosinic-polycytidylic acid (5 ng/mL) for 24 hours revealed the presence of caspase-9 and caspase-8 active subunits [1]. Polyinosinic-polycytidylic acid sodium salt, ready for injection by resuspension in sterile saline at a concentration of 2 mg/mL, heated to 50 °C to guarantee total dissolution and allowed to naturally cool to room temperature to guarantee correct dissolution of double-stranded RNA annealing. Until used, polyinosinic-polycytidylic acid should be kept refrigerated at -20 °C [3]. |

ln Vivo |
When injected with 1205Lu cells, polyinosinic-polycytidylic acid prevents the formation of tumors in immunodeficient NOD/SCID animals. Mice treated with Polyinosinic-polycytidylic acid showed a 50% reduction in human DNA levels [1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
