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，IdeS Protease全称免疫球蛋白G降解酶是由人类致病菌酿脓链球菌产生并分泌至胞外的一种半胱氨酸水解酶。

CD30,又称KI抗原和Tnfrsf8,是一种120kdaI型跨膜糖蛋白,属于tnf受体超家族。成熟的人CD30由一个361AA细胞外域(ECD)和六个富含半胱氨酸的重复,28AA跨膜段和188AA细胞质域。相比之下,小鼠和大鼠CD30缺乏90AA的ECD,并且只包含三个富含半胱氨酸的重复。在ECD的共同区域内,人CD30与小鼠CD30和大鼠CD30的序列认同率分别为53%和49%。人类CD30的交替剪接产生一个等形,包括细胞质域的C132AA。CD30通常在抗原细胞和B细胞上表达。但是,它在霍奇金氏病(红-斯特恩伯格细胞上)、其他淋巴瘤、慢性炎症中,以及自体免疫。CD30与CD30配体/tnfsf8结合,TH细胞、单核细胞、粒细胞和髓质胸腺上皮细胞上表达。产品性质别名CD30;CD30KI-1;CD30Lreceptor;TNFRSF8;D1S166EKi-1;CD30KI-1工会编号P28908-1表达区间及表达系统重组的人CD30/Tnfrsf8蛋白表达于在C-端有标记和AVI标记的HK293细胞。它含有……。分子量大约41.3公里。由于糖基化,蛋白质迁移到70-100kda基于三联页面结果。纯度SDS-PAGE和高效液相色谱法测定的95%。泛素化反应可以修饰蛋白质，调节蛋白质降解。泛素化还影响蛋白质体事件，如蛋白质定位、活性和功能。Fibronectin Active Fragment Control
