Prostaglandin D2 Ethanolamide MaxSpec® Standard

Prostaglandin D2 ethanolamide (PGD2-EA) is a bioactive lipid produced by the sequential metabolism of anandamide by cyclooxygenase (COX) enzymes, in particular by COX-2, and PGD synthase. The biosynthesis of PGD2-EA from anandamide can also be increased when anandamide metabolism is diminished by deletion of fatty acid amide hydrolase. PGD2-EA is inactive against recombinant prostanoid receptors, including the D prostanoid receptor. It increases the frequency of miniature inhibitory postsynaptic currents in primary cultured hippocampal neurons, an effect which is the opposite of that induced by anandamide. PGD2-EA also induces apoptosis in colorectal carcinoma cell lines.PGD2-EA MaxSpec® standard is a quantitative grade standard of PGD2-EA 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 ampulesealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This PGD2-EA MaxSpec® standard is guaranteed to meet identity, purity, stability, andconcentration 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.
