The authors have developed a simple and easy method for site_specific mutagenesis of any genes on plasmids using long distance inverse PCR in the presence of Pfu_DNA polymerase. The efficiency of this method is higher than 90% and the entire procedure can be performed just in one tube. No subcloning is needed. This method is especially useful for obtaining mutant genes on large plasmids such as Ti plasmids used for plant transformation.展开更多

Compared with the anchored PCR RACE, inverse PCR RACE has better specificity and higher amplification.展开更多
