In my view, it's always best to stick as close to the original as possible.

The source text says ...that aliquot quantities of the ethanolic solution (obtained by dissolving 0.5 mg in 10 ml ethanol) were added to each 15 ml of serum

I neglected to mention that my question really pertains to the relationship between the serum and the ethanolic solution. Another variant is "the aliquoted quantities of ethanolic solution were added to each 15 ml of serum". But is there any difference in real terms??
