English

Subject field(s)
  • Genetics
DEF

A method used in gene cloning to separate and identify specific DNA fragments.

OBS

After separation by agarose gel electrophoresis, a nitrocellulose film is placed on the gel surfaces and dry blotting material on the nitrocellulose. Liquid is thus transported from a reservoir beneath the gel through the gel and nitrocellulose filter. The film adsorbs DNA fragments which are then visualized using a complementary DNA or RNA radioactive probe.

French
