IPC: C12P21/00
Filed: 1991-04-16
Granted: 1992-10-22
Abstract: In a method for preparing new biopolymers with improved properties using polymerases, at least one cycle of the following steps is carried out in a series of parallel arrangements to be compared: Nucleic acid sequences or a mixture of similar nucleic acid sequences in the mutant distribution of a quasi species undergo limited mutagenesis in the region of the error threshold. The mixtures are replicated under simultaneous conditions and/or consecutively. The resultant nucleic acids mixtures are compartmented by division. They are then selected by means of a selection system which reflects the properties of interest of the nucleic acid sequence itself or indirectly through its translation product.
