This paper proposes and investigates overlap catenation as a formal model of a special case of cross-pairing PCR, an experimental procedure used to recombine two DNA strands by using the DNA Polymerase enzyme. This study is part of ongoing efforts to provide a formal framework and rigorous treatment of DNA-based information and DNA-based computation. Other studies along these lines include theo...

There are two different co-expression systems including bicistronic; dual-vector or two-promoter to express two different genes simultaneously and also to study protein-protein interactions. Bicistronic system has disadvantages e.g. compared with two-promoter system. In this paper, a simple method based on spliced overlap extension by polymerase chain reaction (SOE-PCR) technique was demonstrat...

In vitro gene chemical synthesis is a powerful tool to improve the expression of gene in heterologous system. In this study, a two-step gene synthesis strategy that combines an assembly PCR and an overlap extension PCR (AOE) was developed. In this strategy, the chemically synthesized oligonucleotides were assembled into several 200-500 bp fragments with 20-25 bp overlap at each end by assembly ...

Here, an efficient cloning strategy for large DNA fragments and for simultaneous assembly of multiple DNA fragments assembly is presented. This strategy is named OEPR (based on Overlap Extension PCR and Recombination in vivo). OEPR cloning is a seamless, restriction- and ligation-independent method. The method takes advantage of both homologous recombination enzymes in E. coli and overlap PCR. ...

In the post-genomic era, the ability to synthesize any arbitrary DNA sequence is increasingly in demand. A bottleneck in current gene synthesis technologies is the associated cost, due primarily to the high cost of oligonucleotides synthesis and post-synthesis sequencing. In the present paper, an improved method for low-cost gene synthesis that combines dual asymmetrical PCR and overlap extensi...
