Cayman'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 the PGD2-MOX ELISA (Item No. 512011). The ELISA offers the convenience of a fast assay while still achieving a sensitivity of ~16 pg/ml and an assay range of 7.8-1,000 pg/ml.
