EndoFree Plasmid Maxi Kit
12362
I work on CRISPR screens where I need to generate viruses using >500 microg plasmids. This kit has exceptional plasmid yield suitable for such experiments. The plasmid is also endotoxin-free. Sometimes, I have used this kit for low-copy plasmids when the yield in midi-prep was low.
