Separating Gel Preparation The total volume between the plates of our gel cassettes is ten ml, so if we prepare 10 ml separating gel mix per cassette we have more than enough. We typically prepare three cassettes per stan . Tape the ends of the casting tray as demonstrated. Set the casting tray on a level surface; you may want to put a paper towel underneath in case it leaks. NEVER pour the gel with the casting tray in the electrophoresis chamber/box
The wells of the gel are made by inserting a comb into the slots in the tray, and as the agarose hardens around the comb, wells are formed. The thicker you pour your gel, the deeper the wells will be. To make a gel, first figure out what volume you want Preparation of gel electrolyte membrane.
