RNA Later-Crystal!!

[Sudheendra Rao N R]

Hi all,
I had kept RNA later at room temperature in an open petri dish by mistake
and i saw almost colorless longitudinal (not smooth but did not have any
defined number of surfaces also) crystals.. of varying length..not soft but
easily breakable
what are they? I tried heating the crystal to 50 degrees for 10 min but it
did not melt..but when i heated to 100 degrees it melted and evaporatorated.
i guess it must be a molecular crystal!
can u guys shed more light on it?

Sudheendra.
