Agarose is composed of long unbranched chains of uncharged carbohydrate without cross links resulting in a gel with large pores allowing for the separation of macromolecules and macromolecular complexes.
A agarosa está composta de cadeas non ramificadas longas de carbohidratos non cargados sen enlaces cruzados, que dan lugar a un xel con grandes poros, que permiten a separación de macromoléculas e complexos macromoleculares.
