agaros
Agaros, commonly referred to as agarose, is a natural polysaccharide derived from agar, a gel-forming carbohydrate extracted from certain red algae such as Gelidium and Gracilaria. It represents the purified, linear fraction of agar that forms gels, and is widely used in laboratory settings for its predictable, inert gel matrix. The polymer is composed of repeating disaccharide units called agarobiose, giving agarose a high molecular weight and a structure that sieves molecules by size.
In solution, agarose is dissolved in warm buffer and then allowed to cool. As it cools, it
The primary use of agarose is in gel electrophoresis, especially for separating DNA and RNA fragments by
Agarose is valued for its natural origin, relative chemical inertness, and ease of handling, making it a
