DOI: 10.1089/thy.2017.0111
Abstract: Background: Difficulties have been reported in quantitating 3-iodothyronamine (T1AM) in blood or serum, and tentatively attributed to problems in extraction or other pre-analytical steps. For this reason, even cell culture experiments have often be performed… read more here.
