There are described stable fluorescent labels comprising a complex of lanthanide metal and a chelating agent comprising a nucleus which is a triplet sensitizer having a triplet energy greater than that of said lanthanide metal and at least two heteroatom-containing groups which form coordinate complexes with lanthanide metals and a third heteroatom-containing group or heteratom in or appended to the triplet sensitizer. Labeled physiologically active materials useful in specific binding assays such as labeled antigens, heptens, antibodies, hormones and the like comprising the stable fluorescent labels having physiologically active materials adsorbed or bonded thereto are also described.
描述了稳定的荧光标记,包括镧系金属和螯合剂的复合物,该螯合剂包括一个三重态敏化剂的核,其三重态能量大于所述镧系金属,并且至少有两个含杂原子的基团,其与镧系金属形成配位络合物,并且第三个含杂原子的基团或杂原子附加到三重态敏化剂中或附加到其上。还描述了标记的生理活性材料,如标记的抗原、肝素、抗体、激素等,其中包括吸附或与稳定的荧光标记结合的生理活性材料,用于特定的结合测定。
