RE: [Histonet] iron stain on bone marrow-SOLUTIONS

From:"Bonner, Janet"

The 20% Hydrochloric acid solution should be added to the 10% Potassium
ferrocyanide solution - (not 10% potassium ferrocyanide to 20% Hydrochloric
acid solution) when making the 1:1 mixture.

Thanks again to everybody who gave me the information about this stain!
Here comes another question: I couldn't see much iron on my slide, only 
about 2~3 spots per rat bone marrow slide. I fixed them in Methanol for 15 
min, then in freshly mixed stain solution(equal part of 20% HCl and 10% 
potassium ferrocyanide) for 30 min in 50-60C. Then counterstain in Safranin 
after wash. Then wash, air dry then mount.

I was told there should be much more iron. I feel bad now. Could any body 
give me advice or could I ask if it's possible due to the bone marrow 
preparation  since we indeed saw some spots. I didn't prepare the sample.

Thanks and look forward to hear from you there!
