Asymmetric Curves Many bioassay curves are too asymmetric to be fit accurately with the symmetric 4PL, like the bioassay above. The 5PL curve and dilution squared residuals (left two graphs) and the 4PL curve and dilution squared residuals (right two graphs) were...

Curves Without Plateaus at One or Both Ends

by | Jan 8, 2020 | Potency Assays

Curves without plateaus Some assay curves don’t reach saturation plateaus within a usable dose range. Potency assays with curves that do not have plateaus at one or both ends are not an issue with STATLIA MATRIX. Hooks Hooks are often a problem when developing and...
