Dear dr/mr/mrs/miss I am having some problems with dissolving xathine in water at conc. 10 mg/ml for tissue culture growth. It does not dissolve completely, even with prewarm water. Can I dissolve it in other kinds of solvents ?. Could any of you who know please tell me how to do that. Many thanks in advance. Sincerely, Dzung Diep dbdiep at uvic.ca
