Oligonucleotide directed mutagenesis

Hello everyone, I have a question about Oligo-N directed mutagensis. after the primer is set and the DNA(plasmid) is replicated, this Hetroduplex is moved into a bacterium (Ecoli). theoretically when the cells replicate each DNA piece (mutated DNA & WildType DNA) will have equal chance of segreg...

Re: problem with cloning/restriction digest

Depending on which table you want to use, NdeI requires 7 extra bases to cut a small oligonucleotide, or at least 6 extra bases to be able to efficiently cut an NdeI site near the end of a linear fragment. XmaI isn't nearly so sensitive to being near an end--it only ...

Re: problem with cloning/restriction digest

... with a simple phenol extraction/ethanol precipitation step instead since the smaller nucleiotides don't precipitate as efficiently as the larger oligonucleotide, but usually you do a gel purification to be safe. You also digest a few micrograms of pET30 with NdeI/XhoI and purify the digested ...
