Oxytocin and each of the three oxytocin fragments (in Arbor Assays’ assay buffer) were measured with no extraction and after one of two solid-phase extractions: HLB or MCX. Both extractions retain most of the oxytocin present in spiked buffer (HLB: 100%, MCX 93%). However, the extractions eliminate most of the signal measured for each fragment of oxytocin, with the MCX extraction removing more of oxytocin 2–9 than the HLB extraction. Note that the actual starting concentrations for each fragment are higher than their measured concentrations (OT 2–9: 2500 pg/ml; OT 4–9: 4000 pg/ml; MIF-1: 100 000 pg/ml).
