Combination Primer Polymerase Chain Reaction for Multi-Site Mutagenesis of Close Proximity Sites

摘要

We describe a rapid and efficient polymerase chain reaction procedure for multi-site-directed mutagenesis for cases in which the sites to be mutated are in close proximity. The combination primer polymer chain reaction method is based on a multi-site directed mutagenesis protocol together with a splicing by overlapping extension polymerase chain reaction protocol. several different combinations of multiple mutations were successfully performed with this method and are reported in this study.
