Abstract
Abstract A method for the radioimmunoassay of PGE 1 -type and PGE 2 -type compounds and PGX is disclosed which utilizes antibodies formed against a prostaglandin mimic. Conjugates are disclosed which are formed by attaching a prostaglandin mimic to a carrier molecule. Antibodies are disclosed which are specific against PGE 1 -type and PGE 2 -type compounds, PGH 2 , and PGX. Complexes are disclosed which are formed by binding an antibody raised against a prostaglandin mimic with its corresponding authentic prostaglandin.
