Abstract
Conjugationally extended hydrazine compositions of the formula (RR)N(H)(NH), fluorescent hydrazone compositions of the formula (RR)NN═C(RR), methods of the formation of hydrazones from the reaction of conjugationally extended hydrazines with conjugationally extended carbonyls and methods of their use in assays systems are described. Use of these conjugationally extended hydrazine and oxime compositions for direct calorimetric and fluorometric assays wherein a chromophore or the fluorophore is incorporated into the linker that is positioned between a reactive linking moiety and a biotin molecule. More specifically the linker comprises one molecule of a high affinity binding pair such as for example biotin of the biotin/avidin high affinity binding pair, connected to a spacer molecule such as for example a length of polyethyleneglycol followed by a pro-chromophoric, chromophoric, pro-fluorescent or fluorescent moiety connected to an amino-, thiol- or carbohydrate-reactive moiety such as for example succinimidyl, maleimido or aminoxy group respectively, that may covalently link to a biomolecule.
