This immunostimulant activity makes Poly I:C a useful vaccine adjuvant and is used in vaccine formulations.  Poly I:C and its stabilized analogs (e.g., poly-ICLC) are also being actively researched for their dual role in oncology: directly targeting tumors and acting as immune potentiators. For example Poly I:C can induce apoptosis in tumor cells and stimulate immunogenic cell death and is therefore being explored alongside chemotherapy, radiotherapy, and checkpoint inhibitors, helping to overcome resistance mechanisms and strengthen treatment outcomes. We can supply PolyI:C to all stages of your project - from R&amp;D and preclinical phases right up to GMP commercial manufacture.
