    • The invention relates to a method for the exponential amplification of molecular matrices, comprising the following steps: (a) binding the molecular matrices to the surface of a solid phase using a reversible linker on the matrix; (b) adding matrix fragments, one of the fragments having an optionally protected linker unit; (c) synthesising copies of the matrix; (d) removing excess matrix fragments and reaction auxiliaries; (e) detaching the copies from the matrices; and (f) populating free binding sites on the solid phase with synthesised matrix copies. The invention also relates to a method for chemical evolution through exponential amplification of molecular matrices, comprising one or more of the following evolution cycles: (1) selection of a subpopulation of molecular matrices from a combinatorial original library; and (2) amplification and mutation of the selective matrices for providing a mutant library, comprising one or more of the amplification cycles (a) to (f) defined above.
    • 本发明涉及分子矩阵的指数扩增方法,其包括(a)借助模板上的可逆接头将分子基质结合至固相表面; (b)加入模板片段,其中片段之一具有任选保护的接头部分; (c)模板拷贝的合成; (d)除去过量的模板片段和反应助剂; (e)将副本从矩阵中分离出来; 和(f)通过合成的模板拷贝在固相上定殖游离结合位点。 本发明进一步涉及通过指数扩增包含一个或多个进化周期的分子模板的化学进化方法(1)从组合文库中选择分子模板子集; (2)选择性模板的扩增和突变以提供包含如上定义的一个或多个扩增循环(a)至(f)的突变体文库。
