What's the maximum temperature at which small RNA (100-200nt) will lose its secondary structure without complete degradation?

I have some RNA transcripts about 130nt long on a Bioanalyzer run, and they should be closer to 100nt. I think it's due to secondary structure. What's the maximum temperature at which I can...

Hexane (and heptane) are non-polar liquids which normally wet most solids very well. It may be that your ITO is hydrophilic and thus hexane is not a suitable continuous phase. The size and density for ITO is probably more relevant for stabilization (i.e. lack of settling). Have you conducted a Stokes' Law equation to get an estimate of the size of particles that may remain in suspension?
