Background:
15-keto Prostaglandin E2 (15-keto PGE2) is a metabolite of PGE2 formed by 15-hydroxy PGDH . In vivo, 15-keto PGE2 is essentially inactive. It has an attenuated affinity for the EP4 and EP2 receptors compared to PGE2 (Ki = 2,600-15,000 nM for the inhibition of PGE2 binding compared to a Kd = 1 nM for PGE2).15-keto PGE2 MaxSpec® standard is a quantitative grade standard of 15-keto PGE2 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 15-keto PGE2 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.
