Provided is a binding protein, which comprises a protein functional region A and a protein functional region B, both of which target different antigens or different epitopes of antigens. The protein functional region A is Fab; the protein functional region B is VH; and the binding protein ...
这些结构域可通过κ轻链与蛋白A或蛋白G(包括IgG,IgM,IgA,IgE和IgD)结合至更宽范围的Ig类别。蛋白L还结合单链可变片段(scFv)和含有κ轻链的Fab片段。当使用复杂的生物样品时,磁珠上专有的封闭剂可最大限度地减少或消除珠粒表面上的非特异性结合。 PuriMag G-Pro的特点: l 高效率 – 与其它供应商的磁珠...
9. Fab-arm exchange(FAE) 受到人体 IgG4 抗体在生理条件下自然发生的半抗体随机交换过程的启示,GenMab 公司开发了 FAE(Fab-arm exchange)双功能抗体技术。在两个目标抗体 IgG1 重链 CH3 区分别引入 K409R 和F405L 两个点突变,就能够形成类似于IgG4 抗体的半抗体交换重排。将突变后的两个不同 IgG1 抗体在...

摘要：Provided are Staphylococcal protein A (SpA) variants for binding immunoglobulin (Ig), comprising a polypeptide which varies by one or more amino acids from the amino acid sequence of a natural variable heavy chain III ("VH3") Ig-Fab binding region ("binding region") of SpA, wherein ...
除用于含Fc的抗体和结构体之外,Protein A填料Amsphere A3还可用于纯化VHH单域抗体等形式的抗体片段、包含VH3结构域的结构体(如Fab)及不同的融合蛋白(如单链可变片段)。这些结合靶标的概述见图12。基于Protein A的填料具有熟知的耐用性、高...
特别是对于VHH sdAb,与Ablynx NV合作筛选出110种分子,其中99%显示与Amsphere A3 Protein A配基结合。相互作用的残基位于框架区(因此不参与抗原结合)并且与Fab中的VL并不相互作用,基于这一事实,有可能会将非Protein A相互作用性Ab片段诱变成结合剂(Fridy等,2015;Henry等,2016)。
