Add ready-to-use solution Ambion™ NorthernMax™ Formaldehyde Loading Dye to RNA sample (3 solutions: 1 sample ) and heat briefly. Samples can then be loaded at any time. Ethidium bromide can be added to the sample if necessary. 6 tubes, 1 mL each.

All Ambion™ gel loading solutions are rigorously tested for non-specific endonuclease activity, exonuclease activity, RNase activity and function. These solutions are the same ones we use in-house and in our kits.
