Bioassay for cat lung parenchymal tissue: following 15 min exposure to 10−7, 10−6 or 10−5 M PGF2α 1-OH: the physiological solutions were sampled and bioassayed using radioligand binding competition studies vs [3H]-17-phenyl PGF2α at recombinant human FP receptors. Competition afforded by PGF2α, the potential metabolite of PGF2α 1-OH, was evaluated for comparison. Points represent mean values±s.e.mean; n=3 experiments performed in duplicate.
