Purifying DNA Bands from Agarose Gels
Description
Agarose gel electrophoresis can be used to purify DNA bands after separation by size. In gel extraction, the DNA fragment of interest is cut from the gel and cleaned before later use. This is especially useful in cloning, where pure DNA is needed before ligation, the joining step that links DNA pieces together.

Transcript
La electroforesis en gel de agarosa es una técnica comúnmente utilizada para separar moléculas de ADN por su tamaño.
La agarosa, un polisacárido derivado de las algas rojas, se agrega a un tampón como Tris-acetato EDTA (TAE) o Tris-borato EDTA (TBE) y se disuelve por calentamiento.
Comúnmente, 1 gramo de agarosa se disuelve en 100 ...
