Background:
Base treatment of human seminal plasma extracts converts the 19-hydroxy PGE compounds present in the sample into the corresponding PGB compounds generating strong conjugated dienone chromophores. This method has been employed to provide a rapid, UV-based analytical method for PGE quantitation. Due to its chemical stability and strong UV absorbance at 278 nm, 19(R)-hydroxy PGB2 is also used as an internal standard in extractions and HPLC to determine recovery of arachidonic acid metabolites.
