A binding agent of the Formula A-a′:a-S-b:b′-B:X(n), wherein A as well as B is a monovalent binder, a′:a as well as b:b′ is a binding pair wherein a′ and a do not interfere with the binding of b to b′ and vice versa, S is a spacer of at least 1 nm in length, :X denotes a functional moiety bound either covalently or via a binding pair to at least one of a′, a, b, b′ or S, (n) is an integer and at least 1, — represents a covalent bond, and the linker a-S-b has a length of 6 to 100 nm. Also disclosed are methods of producing such binding agent and certain uses thereof.
式 A-a′:a-S-b:b′-B:X(n)的结合剂,其中 A 和 B 是单价结合剂,a′:a 以及 b:b′ 是一对结合剂,其中 a′和 a 不干扰 b 与 b′的结合,反之亦然,S 是长度至少为 1 nm 的间隔物,:X 表示与 a′、a、b、b′或 S 中的至少一种共价结合或通过结合对结合的官能团,(n)为整数且至少为 1,- 表示共价键,连接体 a-S-b 的长度为 6 至 100 nm。还公开了生产这种结合剂的方法及其某些用途。
