Detection of Human Hematopoietic Prostaglandin D Synthase/HPGDS by Western Blot. Western blot shows lysates of KG-1 human acute myelogenous leukemia cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Hematopoietic Prostaglandin D Synthase/HPGDS Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6487) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Hematopoietic Prostaglandin D Synthase/HPGDS at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Hematopoietic Prostaglandin D Synthase/HPGDS

Prostaglandin D Synthase (PGDS) catalyzes the conversion of prostaglandin (PG) H2 to PGD2, which is a major prostanoid produced in a variety of tissues. Two types of PGDS have been isolated; the glutathione-dependent hematopoietic PGDS (HPGDS) and the glutathione-independent lipocalin‑type PGDS (1). HPGDS is a cytosolic enzyme that is expressed in mast cells and antigen presenting cells (2, 3). It is the only mammalian member of the class Sigma glutathione S‑transferase, showing a broad specificity towards standard transferase substrates (4). The PGD2 produced by HPGDS is involved in many physiological processes such as maintaining body temperature, promotion of sleep, inhibition of platelet aggregation and bronchoconstriction (5). It also functions in immune response and acts as a mediator in allergy and inflammation (6). HPGDS‑specific inhibitors may be therapeutically useful anti‑allergic and anti‑inflammatory drugs.
