| | Definition: | | 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. A typical gel is about 1% agarose. Agarose is more porous than acrylamide and is sold in different grades; the lower its sulfate content, the more highly purified it is. |
