【摘要】 目的纯化兔抗人RBBP10多克隆抗体。方法在大肠杆菌中,表达重组PTC-hRBBP10融合蛋白,表达产物以直链淀粉树脂亲合柱和superose 12凝胶柱过滤纯化,将纯化的PTC-hRBBP10偶联于NHS-activated SepharoseTM上,制备亲合层析柱,纯化兔抗人RBBP10多克隆抗体。结果①表达、纯化的PTC-hRBBP10的相对分子质量(Mr)为80×103,纯度为95%;②从抗血清中纯化获得可与PTC-hRBBP10特异性结合的兔抗人RBBP10多克隆抗体。结论获得了特异性较好的纯化兔抗人RBBP多克隆抗体,为进一步研究该蛋白质的功能提供了条件,为肿瘤的诊断和治疗提供了新的理论和手段。更多还原

【Abstract】 Objective To purify rabbit anti-hRBBP10 polyclonal antibody.Methods The recombinant fusion protein PTC-hRBBP10 was expressed in the E.coli and was purified through amylose resin chromatography column and superose 12 gel fitration .The purified PTC-hRBBP10 was coupled to the NHS-activated sepharoseTM to prepare affinity chromatography column to purify rabbit anti-hRBBP10 polyclonal antibody. Results ① PTC-hRBBP10 was expressed and purified successfully with relative molecular mass(Mr) of 80×103 and its purity could reach about 95%.② Purified Rabbit anti-hRBBP10 polyclonal antibody could bind Specifically to PTC-hRBBP10.Conclusions With better specificity, The purified rabbit anti-hRBBP10 polyclonal antibody provide condition for studying the function of the protein, and helps to develop new techniques of tumor diagnosis and treatment.更多还原
