LTD4-d5
产品描述:
Leukotriene D4-d5 (LTD4-d5) is intended for use as an internal standard for the quantification of LTD4 (Item No. 20310) by GC- or LC-MS. LTD4 is an active metabolite of LTC4 (Item No. 20210) and a constituent of slow-reacting substance of anaphylaxis (SRS-A).{541,589} It is formed via metabolism of LTC4 by γ-glutamyl transpeptidase. Like LTC4, LTD4 (0.01-0.1 pM) induces contractions in isolated guinea pig parenchymal strips and tracheal spirals.{396} In vivo, LTD4 increases insufflation pressure, a marker of bronchoconstriction, in anesthetized guinea pigs by 100% when administered at a dose of 89 pmol per animal.{4157} It also increases vascular permeability in guinea pig skin when administered intradermally at a dose of 0.1 pmol per animal.
