Polycytidylic acid (poly C) is a synthetic RNA molecule that plays a crucial role as a research reagent in various biomedical disciplines. Its unique chemical structure and biological activities make it an indispensable tool for scientists investigating complex biological processes, particularly in the areas of immunology and virology. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted provider of high-quality polycytidylic acid, supporting the critical work of researchers worldwide.

At its core, polycytidylic acid is a polymer of cytidylic acid units. While it can function independently, its most significant applications in research stem from its ability to form double-stranded RNA (dsRNA) structures, most notably when paired with polyinosinic acid (poly I) to create poly(I:C). This dsRNA molecule is a powerful activator of the innate immune system, mimicking viral RNA and triggering a cascade of defense mechanisms without the need for live viral agents.

The activation process involves specific cellular receptors, such as Toll-like receptor 3 (TLR3) and MDA5. Engagement of these receptors initiates intracellular signaling pathways that lead to the production of crucial signaling molecules, including interferons (IFNs) and various cytokines. These molecules are vital for establishing an antiviral state within cells, inhibiting viral replication, and enhancing the activity of immune cells that target infected cells and pathogens. Understanding the precise polycytidylic acid mechanism of action is fundamental for many research endeavors.

The utility of polycytidylic acid as a biomedical research reagent is vast. It is employed in studies investigating immune system modulators, exploring the development of new vaccines, and developing innovative antiviral therapies. The research into antiviral polynucleotides, with poly C as a key example, continues to push the boundaries of what is possible in combating infectious diseases. NINGBO INNO PHARMCHEM CO.,LTD. ensures the high purity of its polycytidylic acid, presented as a white to off-white powder with an assay of ≥90.0%, guaranteeing its suitability for demanding research applications.
