Application(s): positive control for WB · Source: human recombinant N-terminal GST-tagged protein expressed in E. Coli · M_r: 46 kDa (GST-tagged), 20 kDa (native) · Prostaglandin D synthase (PGDS) 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 PGDS have been identified, namely the lipocalin-type enzyme (β-trace) and the hematopoietic enzyme.^1,2,3 Lipocalin-type PGDS is localized in the central nervous system and male genital organs of various mammals and the human heart. This enzyme has been identified as β-trace, which is a major protein in human cerebrospinal fluid.¹
