Recombinant Human Prostaglandin D2 Synthase 21kDa (brain), His-tagged

• Cat.No.: PTGDS-2501H
• Product Overview: Recombinant human PTGDS protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques. MW: 20.9 kDa.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 23-190aa
• Description: PTGDS is a glutathione-independent prostaglandin D synthase that catalyzes the conversion of prostaglandin H2 (PGH2) to postaglandin D2 (PGD2). It is likely to play important roles in both maturation and maintenance of the central nervous system and male reproductive system. PTGDS is the most abundant protein in the cerebral spinal fluid and recent evidence suggests that PTGDS acts as a beta-amyloid chaperone and may have a role in the deposition of Ab plaques in Alzheimer"s disease.
