Abstract:

目的构建人可溶性晚期糖基化终产物受体(hsrage)his融合蛋白表达载体并在原核细胞表达与纯化。方法pcr扩增hrage基因编码区的胞质外段,利用分子克隆技术将其重组于pet-14b载体中。利用酶切、序列分析鉴定克隆正确性。转化大肠杆菌bl21(de)3,用异丙基b-d硫代半乳糖(iptg)诱导融合蛋白表达。以尿素对获得的包涵体进行处理,用金属螯合亲和层析的方法纯化融合蛋白并进行复性。以western印迹和elisa法对融合蛋白的免疫原性及与age的结合活性进行鉴定。结果克隆的hsrage完全正确,经过表达与纯化,获得了相对分子质量约45000的融合蛋白。纯化得到的变性蛋白经复性后可被相应抗体识别。所得到的hsrage具有与age相互结合的活性,并能够抑制age诱导的内皮细胞nf-kb的表达。结论成功地构建了hsrage融合蛋白原核表达载体且获得高效表达,得到大量的复性蛋白;该蛋白具有特异的免疫原性,保持与age的结合活性,并能够有效阻断age-rage相互作用。
