Generally, I used to have a descrete assay working conc that is anywhere between 10 and 100 times more concentrated than the Rel subs working solution. This is turn would be anywhere between 10 and 100 times more concentrated than the LOQ solution. As long as the range is linear, there should be no problem no matter what concs you choose.
Thanks.
Elliot.
