Abstract: A bivalent binding agent, capable of binding a polypeptide dimer, consisting of two monovalent binders linked to each other via a linker, the first monovalent binder binds an epitope of a first target polypeptide comprised in said dimer and the second monovalent binder binds to an epitope of a second target polypeptide comprised in said dimer. Each monovalent binder has a Kdiss in the range of 5×10−3/sec to 10−4/sec, and the bivalent binding agent has a Kdiss of 3×10−5/sec or less. Methods of making and using such bivalent binding agent in histological staining procedures are also disclosed.

Abstract translation: 能够结合多肽二聚体的二价结合剂，其由通过接头彼此连接的两个单价结合物组成，所述第一单价键合物结合包含在所述二聚体中的第一目标多肽的表位，并且所述第二单价键合物结合表位 的包含在所述二聚体中的第二目标多肽。 每个一价粘合剂的Kdiss在5×10-3 /秒至10-4 /秒的范围内，二价结合剂的Kdiss为3×10-5 /秒或更小。 还公开了在组织学染色方法中制备和使用这种二价结合剂的方法。
