A tetra-functional compound contains a ligand-binding moiety (A) or ligand, a reactive moiety (D), a cleavable moiety (E), and a biotin tag (B), which are linked optionally via a spacer, wherein the ligand-binding moiety (A) is an activated functional group such as an amine-reactive group, or a reactive functional group such as -COOH; the reactive moiety (D) is a group having the structure of a compound such as 2-aryl-5-carboxytetrazole; the cleavable moiety (E) is a group having the structure of a compound such as 1-(4,4-dimethyl-2,6-dioxocyclohex-1-ylidene)ethyl; and the spacer is a group such as a linear or branched alkylene group having one or more carbon atoms, substituted with a crosslinking group.
一种四官能团化合物包含一个配体结合基团(A)或配体、一个反应基团(D)、一个可裂解基团(E)和一个生物素标签(B),它们可选择通过间隔物连接,其中配体结合基团(A)是一个活化的官能团,如胺反应基团,或一个反应性官能团,如-COOH;活性基团(D)是具有 2-芳基-5-羧基四氮唑等化合物结构的基团;可裂解基团(E)是具有 1-(4,4-二甲基-2,6-二氧代环己-1-亚基)乙基等化合物结构的基团;以及间隔物是具有一个或多个碳原子并被交联基团取代的线性或支链烯基等基团。
