"BioTools" refers to applications of DNE as molecular biology or cell engineering reagents.
BioTools for Molecular
Biology. Engineered DNE meganucleases can be used for
cloning and molecular analysis purposes in much of the same ways as
conventional restriction enzymes. The important difference, of course,
is that meganucleases recognize much rarer DNA sequences than
restriction enzymes. This makes them particularly well suited to the
manipulation of extremely large DNA sequences such as intact genomes.
Importantly, DNE meganucleases cleave to leave 4 basepair 3' overhangs
suitable for "sticky-end" cloning.
BioTools for Cell and Animal
Engineering. Engineered DNE meganucleases are commonly
used to engineer cell lines to generate disease models or to produce
optimized cell lines for the biomanufacturing of protein vaccines and
therapeutics. The high efficiency of DNE makes it possible to quickly
generate cell lines with multiple genetic changes or to produce large
numbers of isogenic bioproducer cells without the need to clone from a
single cell. DNE also enables the production of genetically engineered
animal models that precisely mimic human disease genotypes.
