描述了使用二碘甲状腺原氨酸和三碘甲状腺原氨酸作为 125I 受体合成单碘化 3,5,3'-125I-T3 和 125I-T4 的氯胺 T 技术。通常可以获得 3000 mCi/mg T3 量级的比活性,即接近理论最大值。有了这些比之前描述的任何产品至少高 10 倍的高比活性产品,可以直接测定血浆样品的超滤液或透析液中的游离 T3(和 T4)。
A chloramine T technique for the synthesis of monoiodinated 3,5,3′-125I-T3 and 125I-T4 is described using diiodothyronine and triiodothyronine as 125I-acceptors. Specific activities in the order of 3000 mCi/mg T3 are routinely obtained, i.e. approaching the theoretical maximum value. With these high specific activity products, which are at least 10 times higher than any previously described, it becomes possible to determine free T3 (and T4) directly in ultrafiltrates or dialysates of plasma samples.
