I have some GM-CSF from R & D systems that does not give amounts in units/microliter, but rather in micrograms/microliter. It says nothing about how many units are in the bottle on the product sheet either. I am using this to grow bone marrow-derived macrophages, and the recipe calls for 1000 units GM-CSF/ml final concentration in the growth medium. Does anyone know how many mg/ml this is?

Thanks!
