Prostaglandin D2-MOX Express ELISA Kit

Prostaglandin D2 (PGD2) is biosynthesized in the brain by a lipocalin-type PGD2 synthase where it acts in the CNS to promote sleep induction and lowering of body temperature.{328} PGD2 is also the major eicosanoid product of mast cells and is synthesized in large quantities by a hematopoetic-type PGD synthase during allergic and asthmatic anaphylaxis.{8034,7666} Measurement of the parent eicosanoid PGD2 is appropriate in the supernatants of cell cultures, where PGD2 levels may reach several ng/ml, and in CSF, where concentrations of several hundred pg/ml have been measured.{4690} Cayman Chemical’s PGD2-MOX Express ELISA is a competitive assay that permits the rapid measurement of PGD2 from biological samples, requiring only 1 hour incubation and development times for each step. The methodology for the assay is the same as that employed in Cayman’s widely utilized PGD2-MOX ELISA (Item No. 512011). While Item No. 512011 offers superior sensitivity (80% B/B0 ~3.1 pg/ml), the new PGD2-MOX Express EIA offers the convenience of a fast assay while still achieving an 80% B/B0 ~16 pg/ml and an assay range of 7.8-1,000 pg/ml.
