Multiple-site fragment deletion, insertion and substitution mutagenesis by modified overlap extension PCR

Combined Overlap Extension PCR Method for Improved Site Directed Mutagenesis

The combined overlap extension PCR (COE-PCR) method developed in this work combines the strengths of the overlap extension PCR (OE-PCR) method with the speed and ease of the asymmetrical overlap extension (AOE-PCR) method. This combined method allows up to 6 base pairs to be mutated at a time and requires a total of 40-45 PCR cycles. A total of eight mutagenesis experiments were successfully ca...

Versatile PCR-mediated insertion or deletion mutagenesis.

An efficient one-step site-directed deletion, insertion, single and multiple-site plasmid mutagenesis protocol

BACKGROUND Mutagenesis plays an essential role in molecular biology and biochemistry. It has also been used in enzymology and protein science to generate proteins which are more tractable for biophysical techniques. The ability to quickly and specifically mutate a residue(s) in protein is important for mechanistic and functional studies. Although many site-directed mutagenesis methods have been...

A rapid and efficient method for site-directed mutagenesis using one-step overlap extension PCR.

A rapid method is described to efficiently perform site-directed mutagenesis based on overlap extension polymerase chain reaction (OE-PCR). Two template DNA molecules in different orientations relative to only one universal primer were amplified in parallel. By choosing a high dilution of mutagenic primers it was possible to run an overlap extension PCR in only one reaction without purification...

Simultaneous introduction of multiple mutations using overlap extension PCR.

Introduction of multiple mutations can be accomplished through phage M13-based site-directed mutagenesis using several oligonucleotides (6). The major drawback of this method is the low efficiency of generating all the intended mutations simultaneously (7,9). The alternative methods for introducing multisite mutations are based on polymerase chain reaction (PCR) (1) and ligase chain reaction (L...
