1. Agarose (agarbiose)
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.

2. Agarose gel electrophoresis
A type of electrophoresis that uses a matrix of highly purified agar to separate large DNA and RNA molecules (generally around 20,000 nucleotide s in size).

3. Algae
This is a large group of diverse unicellular and multicellular aquatic plants; they grow in both fresh water and seawater and are used commercially as a source of thickeners ( agar , agarose , algin , carrageenan ) and pigments such as beta carotene . Some countries harvest them as food; Spirulina is produced by Israel and Mexico, and the Japanese consume some species of Chlorella. Some species of algae are important commercial pests because they clog pipes and foul pools and reservoirs.

4. Electrophoresis (ionophoresis)
A method of separating large molecules (such as DNA fragments or protein s) from a mixture of similar molecules. An electric current is passed through a medium containing the mixture, and each kind of molecule travels through the medium at a different rate, depending on its electrical charge and size. Separation is based on these differences. agarose and acrylamide gels are the media commonly used for electrophoresis of proteins and nucleic acid s. Specific electrophoretic methods include Northern blot , Southern blot , and Western blot .

5. Northern blot (Northern hybridization, Northern blotting)
A technique similar to Southern blotting , though it is used for RNA . In this technique, RNA fragments are transferred from an agarose gel to a nitrocellulose filter, where the RNA is then hybridized to a radioactive probe .
