提出了一种新的无细胞蛋白质合成(CFPS)中蛋白质表面捕获的方法。我们证明了自发自组装的蛋白质BslA到功能化的表面上的CFPS反应室的表面上。我们表明,蛋白质可以共价捕获这样的表面,使用“捕手/标签”技术。重要的是,当通过CFPS在BslA表面上方原位合成时,或者当作为纯蛋白质添加时,可以捕获感兴趣的蛋白质。这种方法的简单性和成本效益表明,它将在基于无细胞的方法中找到许多应用。
We present a new method for the surface capture of proteins in cell-free protein synthesis (CFPS). We demonstrate the spontaneous self-assembly of the protein BslA into functionalizable surfaces on the surface of a CFPS reaction chamber. We show that proteins can be covalently captured by such surfaces, using “Catcher/Tag” technology. Importantly, proteins of interest can be captured either when synthesised in situ by CFPS above the BslA surfaces, or when added as pure protein. The simplicity and cost efficiency of this method suggest that it will find many applications in cell-free-based methods.
