Polyinosinic acid is a single stranded RNA analog which is combined with polycytidylic acid (poly C) 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.

Nonadecanoyl coenzyme A is a fatty acid that is produced by the bovine liver and has been shown to have anabolic effects. Nonadecanoyl CoA is involved in the synthesis of various lipids, such as phospholipids, cholesterol, and glycolipids. It also plays a role in biosynthesis of fatty acids and in regulating ATP production. Nonadecanoyl CoA is synthesized from acetate by the enzyme acetyl-CoA carboxylase (ACC). ACC catalyzes the conversion of acetyl-CoA to malonyl-CoA, which can then be used for fatty acid synthesis. Nonadecanoyl CoA has been found to play an important role in regulating mitochondrial function through its ability to activate long-chain acyl-CoAs desaturase (LCAD). LCAD converts long-chain acyl-CoAs into their corresponding dicarboxylic acids.
