Background:

(±)11(12)-EET is biosynthesized in rat and rabbit liver microsomes by CYP450.1,2 (±)11(12)-EET has been shown, along with (±)8(9)-EET , to play a role in the recovery of depleted Ca2+ pools in cultured smooth muscle cells.3(±)11(12)-EET MaxSpec? standard is a quantitative grade standard of (±)11(12)-EET that has been prepared specifically for mass spectrometry or any application 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 (±)11(12)-EET MaxSpec? 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.
