I have a problem with bone marrow aspirate controls. The problem is that we are limited to the amount of controls we can collect.  Even though the tissue control is working if the aspirate control (which are difficult to obtain) does not work we are being asked to repeat the stain until we find a aspirate control that is acceptable. Since I can not guarantee the aspirate control contains an adequate amount of Fe, I will be wasting time and reagents. 
Can anyone give feedback on how they process stains on bone marrow's, do you only use a tissue control, does anyone know where bone marrow aspirate controls -positive for Iron -can be purchased commercially?
