blue-white screen
名詞
(biology)
A
screening
technique
for
the
rapid
detection
of
recombinant
bacteria
in
vector-based
molecular
cloning
experiments.
DNA
of
interest
is
ligated
into
a
vector,
which
is
then
inserted
into
a
host
cell;
these
are
grown
in
the
presence
of
X-gal.
Cells
transformed
with
vectors
containing
recombinant
DNA
will
produce
white
colonies;
cells
transformed
with
non-recombinant
plasmids
(i.e.
only
the
vector)
grow
into
blue
colonies.
日本語の意味
遺伝子組み換え実験において、ベクターに組み込まれた目的DNAを含む組換えプラスミドと、非組換えプラスミドを区別するためのスクリーニング技法。具体的には、目的DNAが組み込まれた細胞はX-gal存在下で白色のコロニーを形成し、組み込まれていない細胞は青色のコロニーを形成することで区別される。
