我们描述了一种方法,DNA阵列到蛋白质阵列(达帕),它允许使用无细胞蛋白质合成直接从DNA阵列模板“打印”复制蛋白质阵列。从单个DNA阵列可以获得至少20个拷贝的蛋白质阵列。达帕消除了对单独的蛋白表达、纯化和点样的需要,并且还克服了表面结合蛋白的长期功能性储存的问题。
We describe a method, DNA array to protein array (DAPA), which allows the 'printing' of replicate protein arrays directly from a DNA array template using cell-free protein synthesis. At least 20 copies of a protein array can be obtained from a single DNA array. DAPA eliminates the need for separate protein expression, purification and spotting, and also overcomes the problem of long-term functional storage of surface-bound proteins.
