This linear galactan is created by purifying agar, when it is heated and cooled, it forms a gel that is used as a support for many types of electrophoresis and immunodiffusion (agarbiose). A typical gel is about 1% agarose.

Agarose is more porous than acrylamide and is sold in different grades, the lower its sulphate content, the more highly purified it is.
