Question about specific factor combination in screening DoE (e.g. DSD)
Dear community, I do a lot of protein buffer formulation screens with DoE and one important parameter is the buffer molecule (e.g. Phosphate, Tris, etc.) and its specific pH range.Is there any possible design were I can test several buffer molecules in their pH range (e.g Histidin between pH 5.5 to pH 7 and Tris between pH 5 to pH 9) in one design experiment? The problem which I have is, that I ca...
