The synthesis of novel TbIII labels suitable for protein labelling are reported. Their luminescence properties as antibody conjugates were measured and compared to the results of corresponding TbIII chelates of the parent ligand structures. When the lowest triplet-state energy level of the parent donor ligand was over 23000 cm−1, i.e., the energy gap between the 5D4 level of TbIII and the lowest triplet-state
报道了适用于蛋白质标记的新型Tb III标记的合成。测量了它们作为抗体缀合物的发光特性,并将其与母体配体结构的相应Tb III螯合物的结果进行了比较。当母体供体配体的最低三重态能级超过23000 cm -1时,即Tb III的5 D 4能级与配体的最低三重态能级之间的能隙超过2600 cm -1,发现具有较长衰减时间(τ= 1.35–2.93 ms)和高发光产量(ϵ。Φ= 3770–4560)的标记衍生物适用于生物亲和力测定。
