特异性结合的单克隆抗体1。与Rho1D4抗体结合的表位可以作为针对膜蛋白的超高特异性纯化标记。通过基因修饰可在欲研究的目标(膜)蛋白C端加上Rho1D4标记。一旦加载上该序列,即可用装载有Rho1D4抗体的亲和基质去捕获目标蛋白,随后添加Rho1D4肽,通过竞争性结合基质抗体的方式来洗脱目标蛋白。采用这种方法,相比改变pH值等其他洗脱方式,更加地温和。图1:假设有3个跨膜域的膜蛋白。Rho1D4标签加到膜蛋白C端,它的序列是T-E-T-S-Q-V-A-P-A2) Rho1D4的历史Rho1D4的表位
, renaturation 外源基因在大肠杆菌中的高表达常常导致包涵体的形成,虽然包涵体具有富集目标蛋白质、抗蛋白酶、对宿主毒性小等优点,但包涵体蛋白质的复性率一般都很低,而分子伴侣、低分子量添加物等在复性过程中的应用及新的复性方法的建立都大大提高了重组蛋白质复性产率。 一、包涵体: 1.1包涵体的定义、组成与特性: 包涵体是指细菌表达的蛋白在细胞内凝集,形成无活性的固体颗粒。 一般含有50%以上的重组蛋白,其余为核糖体元件、RNA聚合酶、内毒素、外膜蛋白ompC
