A<unk>  is a method routinely used in molecular biology to check for the presence of a DNA sequence in a DNA sample.<unk> ting combines agarose gel electrophoresis for size separation of DNA with methods to transfer the size-separated DNA to a filter membrane for probe hybridization. The method is named after its inventor, the British biologist Edwin<unk> .  Other<unk> ting  methods (i.e., western<unk> , northern<unk> , southwestern<unk>  that employ similar principles, but using RNA or protein, have later been named in reference to<unk> 's name. As the technique was eponymously named,<unk>  should be capitalized, whereas northern and western<unk> s should not.
