在这项工作中,我们提出了一个一步克隆的方法建立抗体噬菌体展示库依赖于II型限制性内切酶。我们表明,具有足够的质量的单链可变片段(scFv)库可以很容易地克隆在一个'无疤痕'的方式,从免疫鸡的抗原特异性抗体的分离是可行的,在三轮选择。此外,我们证明了这种方法的普遍适用性,通过快速构建和淘选VHH单结构域抗体噬菌体展示库免疫美洲驼剧目。
In this work we present a one-step cloning approach for the establishment of antibody phage display libraries relying on type IIs restriction enzymes. We show that single chain variable fragment (scFv) libraries with adequate qualities can readily be cloned in a ‘scar-less’ manner and that the isolation of antigen-specific antibodies from immunized chickens is feasible within three selection rounds. Moreover, we demonstrate the general applicability of this method by rapidly constructing and panning VHH single domain antibody phage display libraries from immunized Llama repertoires.
