Transgenic mice vector construct

I would not do PCR of a construct to use for microinjection, unless you
are sure the PCR did not introduce any artifactual mutations in the
construct especially the promoter and cDNA sequence.  Alternatively, you
could point mutate the construct at the location where you want to
linearise to introduce a restriction site of your interest and then
linearise it.  Hope that helps.

well,  I cannot say anything about the pcr,

for purification, I use the Qiagen kit, and it works quite well, at
least for my purposes.... but then Iuse zebrafish eggs.
  You could also use the standard phenol chloroform extraction foillowed
ny isopropanol/ ethanol precipitation.

Hope that helps
