I asked ambion guys.
they said that RNAlater being super-saturated salt solution, crystallization
is possible if there is any evoparation.
That settles the stuff :)
somewhere i read that RNAlater contains ammonium sulphate
well..it must be something else..i checked out ammonium sulphate
crystals..they are not long..yup but colorless..
