Adenosine 5γ-triphosphate (ATP) is a central component of energy storage and metabolism in vivo. ATP is use in many cellular processes, respiration, biosynthetic reactions, motility, and cell division. ATP is a substrate of many kinases involved in cell signaling and of adenylate cyclase(s) that produce the second messenger cAMP. ATP provides the metabolic energy to drive metabolic pumps. ATP serves as a coenzyme in a wide array of enzymatic reactions.

Certificate of Analysis

Certificate of Origin

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the water content of Product A7699, Adenosine 5´-triphosphate disodium salt hydrate (ATP)? Does the formula weight listed on the website include water?

    The formula weight on the website does not include water as the amount of water in the product will vary from lot to lot. The water content for any specific lot will be reported on the Certificate of Analysis for that lot.

  4. What is the solubility of Product A7699, Adenosine 5´-triphosphate disodium salt hydrate (ATP)?

    ATP disodium salt is soluble in water (50 mg/mL), yielding a clear, colorless solution. This solution is mildly acidic (pH approximately 3.5).

  5. What is the stability of Product A7699, Adenosine 5´-triphosphate disodium salt hydrate (ATP), in solution?

    Aqueous solutions of ATP are stable for months when frozen at -15°C and for approximately one week at 0°C. ADP is the first hydrolysis product formed, with additional hydrolysis leading to the formation of AMP. However, ATP solutions are only stable for several hours at 0 °C when dissolved in a trichloroacetic acid solution. In alkaline solution, it rapidly decomposes to inorganic pyrophosphate and adenosine 5'-phosphate even at 0 °C. This information can be found on the product information sheet (under Documents, above.
