Paired antibodies are two antibodies that can bind to an antigenic molecule at the same time. Specifically:
Paired antibodies are commonly used in sandwich ELISA experiments
An antigenic molecule usually has multiple epitopes, and different antibodies can target different epitopes
When two antibodies are able to bind to different epitopes of the same antigenic molecule at the same time, the two antibodies are called paired antibodies
However, not all antibodies against different epitopes can be paired antibodies. Sometimes, when an antibody binds to an antigen, it may cause the configuration of other binding sites to change, making it impossible for other antibodies to bind properly
Steric hindrance effects may also result in two antibodies with close binding sites not being able to bind to the antigen at the same time
Therefore, the preparation of paired antibodies usually requires two steps: first the antibody is prepared, and then the paired antibody is screened
Screening of paired antibodies is typically performed using a sandwich ELISA method of bispecific antibodies, in which different combinations of antibodies are tested to determine which antibodies can be successfully paired
Paired antibodies have important applications in immunology research and diagnostics, especially in assays that require high specificity and sensitivity.

文献和实验,在中性和弱碱性条件下可以和固定化的金属离子相互作用(如Ni离子,Zn离子,Co离子等),从而达到纯化蛋白的目的。此系统的洗脱方式可以用过三种非特异性步骤达成: 降低pH(4.5-6) b. 加入EDTA C.不同浓度咪唑溶液(20-250mM) 当蛋白洗脱完毕后,使用EDTA使纯化树脂与金属离子分离,即可完成树脂的再生。 Strep-tag®则是基于链霉亲和素(Streptavidin)和生物素这一自然的相互作用,将Strep-tag®II(WSHPQFEK)或Twin-Strep-tag®
