CHROMOPHORES IN THE PREPARATION OF NOVEL TANDEM CONJUGATES
摘要
The inventors herein disclose new heterobifunctional chromophores that are capable of coupling with two distinct moieties. One moiety may be either a signal-enhancing agent or a blocking agent. The second moiety may be one member of a specific binding pair. The invention is based in part on the surprising result that when a chromophore is used as a "cross-linker" between a signal-enhancing agent and a member of a binding pair (essentially being buried between the two), the signal of the chromophore is not quenched. This arrangement, wherein the chromophore acts simultaneously as a cross-linker and a detectable compound, provides significant advantages over previously known compounds since the chromophore is sterically hindered from interacting non-specifically with substances present in the test systems. Moreover, the chromophore can be used as a cross-linker with little or no loss of detectable signal.
