To do electrophoresis, you will need to make a solution called TAE, which is a specific mixture of Tris base, acetic acid, and EDTA. Assuming no errors and no spills, you will need a minimum of 50 ml 1X TAE to make your agarose gel plus 1 liter of 1X TAE for gel running buffer. TAE is normally made as a 50X concentrated stock.
