迄今为止,单链可变片段(scFv)的产生已成为用于在细菌系统中产生完全功能性抗原结合片段的既定技术。抗体工程的进展现在已经促进了更有效和普遍适用的方法来产生Fv片段。基本上,由噬菌体展示产生的scFv抗体可以与标记蛋白质(例如荧光蛋白或碱性磷酸酶)遗传融合。这些具有抗原结合能力和标记活性的双功能蛋白质可以从转化的细菌中获得,并用于生物制剂的一步免疫检测。或者,抗体片段也可用于构建免疫毒素、治疗性基因递送和用于治疗目的的抗癌胞内抗体。本文综述了单链抗体的原理、制备方法及其应用。本文还讨论了单链抗体在乳腺癌研究中的应用前景。
To date, generation of single-chain fragment variable (scFv) has become an established technique used to produce a completely functional antigen-binding fragment in bacterial systems. The advances in antibody engineering have now facilitated a more efficient and generally applicable method to produce Fv fragments. Basically, scFv antibodies produced from phage display can be genetically fused to the marker proteins, such as fluorescent proteins or alkaline phosphatase. These bifunctional proteins having both antigen-binding capacity and marker activity can be obtained from transformed bacteria and used for one-step immunodetection of biological agents. Alternatively, antibody fragments could also be applied in the construction of immunotoxins, therapeutic gene delivery, and anticancer intrabodies for therapeutic purposes. This paper provides an overview of the current studies on the principle, generation, and application of scFv. The potential of scFv in breast cancer research is also discussed in this paper.
