Measuring peripheral oxytocin and vasopressin in nonhuman primates

Abstract: Studying the neural and hormonal changes that modulate behavior is critical to understanding social relationships. Of particular interest is measuring oxytocin (OT) and arginine vasopressin (AVP) peripherally, and preferably, non-invasively, in nonhuman primates. Due to these peptides' neural origin and their stimulation of brain areas that influence social behavior, there has been debate whether peripheral measures in blood, urine, and saliva reflect central levels in the brain. This review elucidates the cha… Show more

“…One aliquot was used for analysis of creatinine. In the second aliquot, 0.5 N phosphoric acid were added to urine at a ratio of 1:10 acid to urine to prevent the breakdown of OT in the sample (Reyes et al, 2014;Ziegler, 2018). All samples were then stored in a freezer at -20°C.…”

“…Even though the company developing this assay states that it can be used for measurements of OT in human urine, serum, plasma, breast milk, saliva, and cerebrospinal fluid samples, our study indicates that there are considerable issues when measuring OT in urine, especially with its accuracy. This should be considered, when interpreting the results of previously published work that has used this assay (reviewed in ( 33 )).…”

“…While in general steroid hormones are thought to be stable when stored at room temperature for about 24 h and for some days at 4°C, freezing of samples as soon as possible following collection is generally recommended ( 43 , 44 ). Other biological markers, such as peptide hormones or gonadotropins, are more susceptible to degradation and besides freezing samples as soon as possible, adding a preservative to prevent degradation is recommended ( 33 , 43 ).…”
