Prostaglandin D Synthase (hematopoietic-type; human recombinant)

Stability : 6 months
Formulation :
A solution in 50 mM sodium phosphate, pH 7.2, containing 20% glycerol, 100 mM sodium chloride, 1 mM DTT and 0.5 mM EDTA
Description : 
Prostaglandin D synthase (PGD synthase) catalyzes the isomerization of PGH2 to produce PGD2. PGD2 induces sleep, regulates nociception, inhibits platelet aggregation, and acts as an allergic mediator. Two distinct types of PGD synthase have been identified, namely the lipocalin-type enzyme (β-trace) and the hematopoietic enzyme. Hematopoietic PGD synthase (H-PGDS) is widely distributed in the peripheral tissues and is localized in the antigen-presenting cells, mast cells, and megakaryocytes. PGD2 is produced by H-PGDS in large quantities by allergen-stimulated mast cells and acts as a pro-inflammatory mediator in allergic reactions. H-PGDS requires glutathione for activity and belongs to the sigma-class of glutathione-S-transferases.
