abstract：:Tandem repeats of single short peptide sequences are useful for many purposes. Here we describe a method called ligation-PCR to construct DNA sequences encoding numerous tandem peptide repeats that can stably produce such repeats in both prokaryotic and eukaryotic cells. The method employs double-strand target monomer...
