An efficient one-step site-directed and site-saturation mutagenesis protocol.
We have developed a new primer design method based on the QuickChange site-directed mutagenesis protocol, which significantly improves the PCR amplification efficiency. This design method minimizes primer dimerization and ensures the priority of primer-template annealing over primer self-pairing during the PCR. Several different multiple mutations (up to 7 bases) were successfully performed wit...
متن کاملAn 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...
متن کاملSaturation site-directed mutagenesis of thymidylate synthase.
We have subjected 12 different codons of a synthetic Lactobacillus casei thymidylate synthase (TS) gene to saturation site-directed mutagenesis to create amino acid "replacement sets" at each of those positions. The target residues were chosen because they are highly conserved and because they are important for the structure and function of the protein as indicated by solution and structural st...
متن کاملA 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...
متن کاملPatch cloning method for multiple site-directed and saturation mutagenesis
BACKGROUND Various DNA manipulation methods have been developed to prepare mutant genes for protein engineering. However, development of more efficient and convenient method is still demanded. Homologous DNA assembly methods, which do not depend on restriction enzymes, have been used as convenient tools for cloning and have been applied to site-directed mutagenesis recently. This study describe...
