[Histonet] Malmberg's fixative

[McCollough, Carol]

Greetings Histonetters:

I have been asked for a recipe for Malmberg's fixative (1:1 ammonium picrate and glycerol).  I cannot find a method for the preparation of ammonium picrate.  Does anyone have a recipe or a commercial source for this nasty?

Thanks very much.

Regards -
Carol
