Hi guys,


Im trying to create point mutation in domain of gene of interest using enzynomics EZ-MIX kit. I believe this kit follow quick-change site directed mutagenesis method; PCR amplification of forward-reserve complemantary primer with the introduction of mutation in the middle of primer, follow by dpn1 digestion.


I am able to get the colonies after transformation but when i sent two clones for sequencing, sequencing result turn outthere is point mutation, but the whole primer region duplicated in both clones. May i know if anyone had experience this and how to overcome this problem. Im thinking sending more clones for sequencing may help.Thanks!!
