摘    要:为制备鸡肝脏型脂肪酸结合蛋白(L-FABP)的多克隆抗血清,并分析L-FABP的组织表达特性,利用RT-PCR扩增L-FABP基因,构建鸡L-FABP基因的GST融合蛋白表达质粒pGEX-4T/L-FABP。将重组表达质粒转化大肠杆菌BL21,IPTG诱导产生GST/L—FABP融合蛋白,用亲和层析纯化目的蛋白,将纯化的GST/L—FABP融合蛋白免疫家兔制备抗血清,并利用此抗血清分析鸡0FABP基因的组织表达特性。诱导得到了1个40ku(14ku L—FABP+26kuGST)的融合蛋白,获得效价较高、特异性强的鸡L-FABP的抗血清。鸡L-FABP的组织表达特性研究结果表明,该基因在肝脏和小肠组织中有较高表达,但在心脏、脂肪、肌肉、肌胃、脾、肺和肾中没有检测到表达信号。

关 键 词:原核表达  抗血清    L-FABP

Abstract:The aim of this study was to prepare the antiserums against chicken liver-type fatty acid binding protein(L-FABP) and analyze expression characteristics of L-FABP.Specific primers were designed to amplify the gene of chicken L-FABP by RT-PCR.The L-FABP gene was then inserted into pGEX4T-1 vector and expressed in Escherichia coli BL21(DE3).The protein was purified by Glutathione Sepharose 4B affinity chromatography and the antiserums against L-FABP was produced by immunizing rabbits.The tissue expression cha...
