利用PCR技术扩增得到编码土豆羧肽酶抑制剂(carboxypeptidaseinhibitorfrompotato,CPI)活性多肽基因,克隆于表达载体pGEX一4T一1的多克隆位点中,得到重组质粒pGCPI,测序后将重组质粒转化到受体茵EscherichiacoliBL21中。重组茵经IPTG诱导表达,超声波破茵后,通过谷胱甘肽sepheroseFF亲和层析柱一步纯化得到融合蛋白,纯度大于97%。融合蛋白经凝血酶切割并分离除去谷胱甘肽一S一转移酶后得到纯度大于98%的重组CPI,ELISA鉴定产物具有免疫原性,体外检测表明其促进纤溶的生物功能与天然CPI无明显差异。
重组肠激酶(rEK)是一种高纯度的重组牛肠激酶轻链片段,氨基酸序列与牛肠激酶轻链一致,有着和天然提取的肠激酶同样特异的酶切位点,切割位点Asp-Asp-Asp-Asp-Lys,可去除位于蛋白N-末端的融合蛋白,以除去不需要的融合标签,同时重组肠激酶(rEK)具有比天然酶更高的切割活性。重组肠激酶为采用重组大肠杆菌分泌表达的高纯度、高活性、高特异的牛肠激酶,不含其他蛋白酶,可以在较宽pH范围(4.5-9.5)和较宽温度范围内有效切割融合蛋白,并且在各种去垢剂和变性剂存在的条件下仍具有部分活性。本品不含标签,由于具有极高酶切活性,酶切反应使用量少,不影响下游蛋白应用,可不考虑除去。产品信息规格100U/200U/500U/1000U/5000U产品性质来源(Source)大肠杆菌表达分子量(MolecularWeight)理论值25.85kDa外观(Appearance)澄清、无色至淡黄色液体酶浓度(EnzymeConcentration)≥5U/uL活性定义(ActivityDefinition)一个活性单位定义为25°C,12-16h,泛素蛋白(Ubiquitin,简称Ub)是一种在真核细胞中普遍存在的小分子蛋白,具有高度保守性。
