Methods of performing assays with long lifetime compounds are disclosed. The long lifetime compounds have a lifetime of 4 ns or longer and relate to the structure:
Linked reactive groups or conjugated substances may generally be located at R
a
, R
b
, or R
c
. Adjacent substituents R
a
and R
b
may form a substituted, 5- or 6-membered heterocyclic group with one ring nitrogen. R
e
and R
f
may both be H, R
e
may be a sulfo group, or adjacent substituents R
e
and R
f
may form a cyclic ring structure. The long lifetime compounds contain at least one sulfo group and at least one ionic group, reactive group, or conjugated substance.
本发明公开了使用长寿命化合物进行测定的方法。这些长寿命化合物的寿命为4纳秒或更长,并与下列结构相关:反应性基团或共轭物质通常可以位于Ra、Rb或Rc处。相邻的取代基Ra和Rb可以形成带有一个环氮的取代的5-或6-成员杂环基团。Re和Rf都可以是H,Re可以是磺酰基,或者相邻的取代基Re和Rf可以形成一个环状结构。这些长寿命化合物包含至少一个磺酰基和至少一个离子基团、反应性基团或共轭物质。
