I just bought a plasmid from addgene, the name is DMP1-GFPtopaz.
However, I could not extract the vector DNA by using Qiagen DNA purification kits from the bacteria.
the bacteria growth was very well at 30 ug/ml carbenicillin.
I know the vector is very big.
I wish someone has handled this plasmid and can give me some suggestions to fix this problem.
Thanks!
