Used for quantitative detection of Iodine Deiodase II (DIO2) in rat biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit is specifically designed for research purposes to measure DIO2 enzyme levels, which plays a key role in thyroid hormone metabolism by converting thyroxine (T4) to the active form triiodothyronine (T3). It is widely applied in endocrinology and metabolic studies involving thyroid function, energy balance, and thermogenesis in rat models. The assay enables high sensitivity and specificity, allowing researchers to monitor changes in DIO2 expression under experimental conditions such as hormonal treatments, metabolic disorders, or developmental stages. Not intended for diagnostic use in humans.
