Gel Electrophoresis of RNA in Agarose and Polyacrylamide Under Nondenaturing Conditions,lecules is left intact during electrophoresis. The first method describes electrophoresis in a 2% (w/v) agarose gel in a dilute, neutral phosphate buffer. The second deals with electrophoresis in a linear gradient of polyacrylamide based on the buffer system of Loening (.).
