摘要：

Background: Lack of specificity of anti-PGE(2) antibodies is a long-standing problem. Given quite a few analogs and low PGE(2) content in biological fluids, it is quite important to simultaneously meet the demands of high specificity and sensitivity. Results: Highly specific anti-PGE(2) antibodies were obtained by combined use of cationic carrier protein and Mannich reaction. The cross-reactivity values of the resultant polyclonal and monoclonal antibodies against eight analogs were <14 and <5%, respectively. Furthermore, we established a highly sensitive ELISA, which could be applied to direct analysis of PGE(2) at the pg/ml level (LOQ = 15.6 pg/ml). Conclusion: We provide an appropriate strategy to develop a highly-specific and sensitive immunoassay for measuring low PGE(2) content in biological samples.
