I don't think it possible for protein purification purpose. There would be no linear correlation between A280 and the protein concentration.
For pure protein analysis, as for minor amount protein used, it is possible.

I know I could figure it out myself if I really tried, but why bother when I have access to so many brilliant minds.... Thanks to all, K
