Eight discrete bands, ranging from 100 to 1,000 bases Higher intensity band at 500 bases for easy reference No need for staining or destaining as loading dye contains ethidium bromide Convenient lyophilized format provides better product stability The Norgen 100 b RNA Ladder is a set of RNA transcripts derived from recombinant DNA templates. This ladder is suitable for precise sizing of small RNA molecules using native or denaturing agarose gels, and can be easily visualized under UV. Contents 2 vials of lyophilized RNA ladder (25 loads each) 1x loading buffer: 33.3% formamide, 11.7% formaldehyde, 0.012% bromophenol blue, 0.05mM EDTA, 0.012% ethidium bromide, and 0.7x MOPS solution 2x loading buffer
