Anti-Prostaglandin J2, 15-deoxy-D12,14-

15-deoxy-Delta12,14-Prostaglandin J2 (15-d-PGJ2) is one of the ultimate dehydration products of PGD2, formed via the intermediate Delta12-PGJ2. 15-d-PGJ2 is physiologically present in body fluids at concentration of 10-12 to 10-9 M, but increases dramatically under stress such as infection and inflammation. 15-d-PGJ2 exerts both pro- and anti-inflammatory effects in a cell-type and concentration-dependent manner, with many of these effects mediated via binding to the gamma isoform of the peroxisome proliferators-activated receptor (PPAR-gamma). 15-d-PGJ2 appears to induce HO-1 expression by a PPAR-gamma-independent mechanism mediated by the generation of reactive oxygen species (ROS). Applications: Suitable for use in ELISA. Other applications not tested. Recommended Dilution: 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. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
