1. This marker was not designed for precise quantification of dsRNA mass.
2. Double-stranded RNA is sensitive to degradation by ribonucleases, even though it is more resistant than single-stranded RNA.
   
   To avoid ribonuclease contamination: wear gloves, use RNase-free water for gels and buffers, wash equipment with detergent and rinse throughly with RNase-free water.
   
   Excessively long run times or high voltage can cause degradation of the bands on the gel. We recommend loading 2-3 µl of dsRNA Ladder, a running voltage of 4-10 V/cm , adding ethidium bromide to gels and running buffer at a final concentration of 0.5 µg/ml to effectively stain the bands during agarose gel electrophoresis.
