The picture above shows a typical gel electrophoresis set up. The clear container in the center of the picture is called a gel electrophoresis chamber. It contains the agarose gel that will be loaded with genetic material‚ as well as a buffer solution. It is connected to a DC power supply via electrodes. This picture was taken at Paw Print Genetics laboratory in Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium

silver-white‚ highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature‚ but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth’s crust‚ and exists in numerous minerals such as feldspars‚ sodalite and rock salt (NaCl). Many salts of sodium are highly water-soluble‚ and their sodium has been leached
