Anti-LPGDS antibodies are protein reagents that detect specific antigens. The LPGDS antigen is another term for the human protein prostaglandin D2 synthase, encoded by the PTGDS gene. The protein is known to catalyze the conversion of PGH2 to PGD2, a prostaglandin involved in smooth muscle contraction/relaxation and a potent inhibitor of platelet aggregation. Canonically, it has an amino acid length of 190 residues and a mass of 21 kilodaltons. Its subcellular localization is in the nucleus, ER, Golgi, cytoplasm, and is secreted. It is notably expressed in the brain and CNS, where it is expressed in tissues of the blood-brain barrier and secreted into the cerebro-spinal fluid. The LPGDS protein is a member of the Lipocalin protein family. Indicated applications for LPGDS antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
