Adenosyl-(3′→5′)-uridine (ApU) is a nucleotide composed of an adenine base linked to a uracil sugar molecule via a 3'-5' phosphodiester bond. Adenosyl-(3′→5′)-uridine (ApU) is involved in biological processes such as gene expression regulation, signal transduction, and protein synthesis.

*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.
