Water-soluble discrete multi-biotin-containing compounds with at least three (3) biotin moieties are disclosed. The water-soluble biotin-containing compounds may additionally comprise one or more moieties that confer resistance to cleavage by biotinidase or that is cleavable in vitro or in vivo. The discrete multi-biotin-containing compounds may include a reactive moiety that provides a site for reaction with yet another moiety, such as a targeting, diagnostic or therapeutic functional moiety. Biotinylation reagents comprising water-soluble linker moieties are also disclosed and may additionally comprise a biotinidase protective group. Methods for amplifying the number of sites for binding biotin-binding proteins at a selected target using multi-biotin compounds also are disclosed.
可溶于水的离散多生物素含有化合物,至少含有三个(3)生物素基团。这些可溶于水的生物素含有化合物可能还包括一个或多个使其对生物素酶的裂解具有抗性的基团,或者在体外或体内可被裂解的基团。这些离散的多生物素含有化合物可能包括一个反应性基团,提供与另一个基团(如靶向、诊断或治疗功能基团)反应的位点。还公开了包含可溶于水的连接基团的生物素化试剂,可能还包括生物素酶保护基团。还公开了使用多生物素化合物扩增在选定靶点上结合生物素结合蛋白的位点数量的方法。
