From:Ryan Dominique Salazar

Hi everyone,
  Please help me on Iron staining. These are my questions:
  -do I need to stain quickly after heating in the hot plate?
  -very pale nuclear fast red (Sigma) stain.
  -Is this OK for my working solution?

  2% hydrochloric acid --------------------------------------------        20.0 ml
  1% potassium ferrocyanide -------------------------------------          20.0 ml

        Prepare just before use and discard after use.
