11β-PGF2α is the primary plasma metabolite of PGD2 in vivo, the levels of which can increase from 6 pg/ml in a normal healthy volunteer to 490 ng/ml in patients with systemic mastocytosis. The normal human urinary excretion of 11β-PGF2α is about 11 ng/mmol creatinine (~400…

8(S)-HETrE is a monohydroxy PUFA produced by rabbit neutrophil lipoxygenase when DGLA is used as a substrate. Although the biological activities of 8(S)-HETrE have not been well characterized, it is expected to behave similarly to 8(S)-HETE.

(±)12-HpETE is one of the six monohydroperoxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid (Item No. 90010) and consists of an equal mixture of the R and S isomers. Reduction of the hydroperoxide yields the more stable hydroxyl fatty acid (±)12-HETE (Item…

Thioetheramide-PC is a structurally modified phospholipid that functions as a competitive, reversible inhibitor of sPLA2. The IC₅₀ value for thioetheramide-PC is 2 µM at a substrate concentration of 0.5 mM. In addition to binding to the catalytic site of sPLA2, thioetheramide-PC…

An internal standard for the quantification of trans-resveratrol by GC- or LC-MS.

A purified enantiomer of (±)9-HETE resulting from non-enzymatic oxidation of arachidonic acid.

11β-PGF2α-d4 contains four deuterium atoms at the 3, 3', 4, and 4' positions. It is intended for use as an internal standard for the quantification of 11β-PGF2α by GC- or LC-MS.

Cloprostenol is a synthetic PGF2α analog and a potent FP receptor agonist. (+)-15-epi Cloprostenol is the 15(S), or 15β-hydroxy enantiomer of (+)-cloprostenol. This epimer is less active by several orders of magnitude as an FP receptor ligand when compared to 15(R)-cloprostenol. However,…

DGLA is a metabolite produced by chain elongation of the essential fatty acid γ-linolenic acid. Ethyl DGLA is an esterified version of the free acid which is less water soluble, but more ammenable for the formulation of DGLA-containing diets and dietary supplements. DGLA has been advanced as…

Isoprostanes are prostaglandin (PG)-like products of free-radical induced lipid peroxidation. Although the isoprostanes derived from arachidonic acid are the best characterized, many other polyunsaturated fatty acids can form isoprostanes. iPF2α-VI is one of dozens of possible stereo- and…
