Comparison of selected MRM Transitions with the ones from literature^a

compound	transitions	signal to noise (S3)	signal to noise (QC4)
PGD2^b	351/271	322	452
PGD2^c	351/189	247	307
6 keto PGF1α^b	369/163	28.0	66.3
6 keto PGF1α^c	369/207	16.0	33.7
TXB2^b	369/169	282	739
TXB2^c	369/195	73.9	203
15 HETE^b	319/219	585	979
15 HETE^c	319/175	221	788

The MS settings for both MRM transitions were optimized representatively before comparison using direct infusion of the standards.
