15(S)-HETE MaxSpec(R) Standard

15(S)-HETE is a major arachidonic acid metabolite from the 15-lipoxygenase pathway. In mammals, 15(S)-HETE is synthesized in the respiratory epithelium, leukocytes, and reticulocytes. 15(S)-HETE is present in µg/ml concentrations in the nasal secretions of allergic rhinitis. 15(S)-HETE MaxSpec(R) standard is a quantitative grade standard of 15(S)-HETE (Cay-34720) that has been prepared specifically for mass spectrometry and related applications where quantitative reproducibility is required. The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This 15(S)-HETE MaxSpec(R) standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product. Note: The amount of solution added to the vial is in excess of the listed amount. Therefore, it is necessary to accurately measure volumes for preparation of calibration standards. Follow recommended storage and handling conditions to maintain product quality.Formal Name: 15S-hydroxy-5Z,8Z,11Z,13E-eicosatetraenoic acid. CAS Number: 54845-95-3.
