Anti-PTGES3 Antibody

PTGES3, also referred to as p23 or cytosolic prostaglandin E synthase 3, is a small chaperone protein of approximately 18.7 kDa that operates both as an Hsp90 co-chaperone in the cytoplasmic steroid receptor folding complex and as a terminal enzyme that converts prostaglandin H2 into prostaglandin E2. This unconjugated rabbit polyclonal IgG reagent from Antibodies.com is supplied as 200 µl of ready-to-use antiserum validated for western blot detection of the endogenous human, mouse, and rat protein. Researchers investigating glucocorticoid receptor signaling, telomerase assembly, prostaglandin E2 biosynthesis, or Hsp90-dependent client maturation can use this reagent to probe lysates for PTGES3 levels and complex composition under varied experimental conditions. The polyclonal format maximizes epitope coverage across the target, supporting robust signal in immunoblotting of cell and tissue extracts. Storage at -20 °C in working aliquots preserves antibody activity across multiple freeze-thaw cycles and extended bench use.
