RNA sample loading buffer is formulated for use in RNA sample preparation for denaturing formaldehydeagarose gel electrophoresis. The solution contains tracking dyes and ethidium bromide, so gel loading buffer and ethidium bromide staining are not required.


Note: This solution contains ethidium bromide that can interfere with transfer of RNA to nylon or nitrocellulose membranes.


Add loading buffer to sample in ratio of 1:2 to 1:5. Just before loading, heat to 65 °C for 10 minutes, then chill on ice.
