I was wondering if anyone could shed some light on how to reduce the specific activity of a compound.
I have a tritiated compound required for my experiment but I worked out at the concentrations I need I would be using a vial for every replicate!
So I need to reduce the specific activity but I am not sure how to do this. Presumably you do this with unlabeled compound? I have some unlabeled compound but its in a powder, I assume I add this to the radioactive compound but won't it affect the concentration?
Also, will you need extra time to count each sample? I currently count at 1 min per sample.
Thanks for the clarification!!
