亲和标签的发展极大地简化了蛋白质的纯化程序。现在有多种亲和标签可用于改善表达、溶解性和/或标签去除。在这一章中,我们描述了一种纯化在大肠杆菌中表达的重组蛋白的方法,该方法使用了一个高度特异的、可诱导的、C末端自动处理的蛋白酶标签。这种方法将亲和纯化、切割和标签分离简化为一步纯化过程,避免了从目标蛋白中去除与外源蛋白酶的融合标签的需要。除了加速蛋白质的纯化外,我们还证明了这种方法可以提高精选蛋白质的表达、稳定性和溶解性。
The development of affinity tags has greatly simplified protein purification procedures. A variety of affinity tags are now available to improve expression, solubility, and/or tag removal. In this chapter, we describe a method for purifying recombinant proteins expressed inEscherichia colithat uses a highly specific, inducible, C-terminal autoprocessing protease tag. This method streamlines affinity purification, cleavage, and tag separation into a one-step purification procedure, avoiding the need to remove fusion tags from target proteins with exogenous proteases. In addition to accelerating protein purification, we show that this method can enhance the expression, stability, and solubility of select proteins.
