Size

£672.00

SKU:: P9053-25M
Purity:: Purified by Protein A affinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Rabbit
Immunogen:: Recombinant human hematopoietic prostaglandin D synthase (H-PGDS).
Format:: Supplied as a liquid in PBS, pH 7.2, 0.02% sodium azide, 50% glycerol.
Extra Details:: 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 (beta-trace) and the hematopoietic enzyme.1,2,3 Lipocalin-type PGD synthase is localized in the central nervous system and male genital organs of various mammals and the human heart. This enzyme has been identified as beta-trace, which is a major protein in human cerebrospinal fluid.4,2 Hematopoietic PGD synthase is widely distributed in the peripheral tissues and is localized in the antigen-presenting cells, mast cells, and megakaryocytes.1 This enzyme, which requires glutathione for activity, belongs to the sigma-class of Glutathione-S- Transferases and is approximately 23 kD in size. Applications: Suitable for use in Immunohistochemistry and Western Blot. Other applications have not been tested. Recommended Dilutions: Immunohistochemistry: 1:1000 Western Blot: 1:200 with 1 hour incubation at RT. (1:500 dilution with overnight incubation at 4°C also produces optimal results.) Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
