Re-crystallising dextran rhodamine

[Trevor Lewis-2]

Does anyone out there have experience re-crystallising dextran
rhodamine? I have been given some dextran rhodamine where the crystals
have all sort of 'melted' together (from poor storage) and so needs to
be dissolved and recrystallised. I expect it is probably straight
forward, but I haven't done it before so thought I would ask for any
tips / tricks.
Thanks,

Trevor
