摘要:
为制备特异性结合猪源Sn受体的纳米抗体分子,采用人工合成猪肺泡巨噬细胞Sn受体胞外区(Sn4D)基因序列,将其克隆至pET-30a载体中,并在大肠杆菌中诱导表达Sn4D蛋白;经Ni柱纯化的Sn4D蛋白作为靶标分子,在T7噬菌体展示的纳米抗体文库中进行3轮亲和筛选;然后从筛选产物中挑选单抗克隆噬菌体进行亲和力、特异性鉴定。结果显示,成功构建了pET-30a-Sn4D重组表达载体,并诱导表达出约50 ku的目标蛋白,Western-blot显示该蛋白具有良好的反应活性;经过3轮亲和筛选,投入产出比逐渐升高,并从筛选产物中鉴定出6株特异性结合Sn4D的纳米抗体分子。该纳米抗体分子的获得为今后进一步开展抗病毒活性的研究奠定了良好基础。
