Polycytidylic acid

Description:

Polycytidylic acid, often abbreviated as poly(C), is a synthetic polynucleotide composed of repeating cytidine monophosphate units. It is a homopolymer of cytidine, which is one of the four nucleotides that make up RNA. Polycytidylic acid is characterized by its ability to form secondary structures, such as hairpins and loops, due to the hydrogen bonding between its bases. This property is significant in various biochemical applications, including its use as a model for studying RNA structure and function. Poly(C) can also serve as a substrate for RNA polymerases and is utilized in research related to gene expression and regulation. Additionally, it has been studied for its potential role in immunostimulation, as it can activate certain immune responses. Polycytidylic acid is soluble in water and exhibits a high degree of stability under physiological conditions, making it a valuable tool in molecular biology and biochemistry. Its CAS number, 30811-80-4, is used for identification in chemical databases and regulatory contexts.

Polycytidylic acid

CAS: 30811-80-4

Polycytidylic acid is a single stranded RNA analog which is combined with Polyinosinic acid to form a stable duplex structure known as Polyinosinic acid-polycytidylic acid (Poly I:C). PolyI:C stimulates the secretion of pro-inflammatory cytokines and type I interferon through its interaction with endosomal Toll-like receptor 3 (TLR-3) and the cytoplasmic receptors melanoma differentiation-associated gene 5 (MDA-5) and retinoic acid-inducible gene I (RIG-I). 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&D and preclinical phases right up to GMP commercial manufacture. Contact our team for custom Poly I:C products.
