Abstract
- A monoclonal antibody against cis-3-hexen-1-ol was prepared and used to separate and/or concentrate Δ17-6-keto-prostaglandin F1α (PGF1α) in the human sera. cis-3-Hexen-1-ol was conjugated with the human serum albumin (HSA) according to the N-succinimidylester method and hyperimmunized to BALB/c mouse. The monoclonal afntibodies were obtained from hybridoma clones established by a fusion between SP2/0-Ag14-k13 mouse myeloma cells and splenocytes of a mouse. A monoclonal antibody, named 4G9-12B, recognized the epitope characteristic for ω3-olefin structure. The 4G9-12B antibody became more specific for Δ17-6-keto-PGF1α than 6-keto-PGF1α by applying inhibition ELISA using amino-residue coating plates. Using the prepared immunoaffinity columns of this antibody, Δ17-6-keto-PGF1α was clearly detected in 6 pg/ml of the human blood sera by GC/MS analysis. These results suggest that the monoclonal antibody to the partial structure of trienoic prostanoid, ω3-olefin unit, and that its immunoaffinity columns are useful in separating and concentrating Δ17-6-keto-PGF1α in the human blood or urine.
