Many researchers generate their mutants by
using commercial mutagenesis kit. However, long sequence(>30
bp) insertion/ deletion/ substitution can not be
achieved by using commercial kit.
it is also very common to
fail mutagenesis reaction for a special plasmid
containing GC-rich region, tight secondary structure region, etc. The success of mutagenesis critically depends on the skills of
researcher.
Moreover, Commercial kit is very costly. We take a simple point mutation for
example:
