Distribution Of Standard Dilution Responses Is the distribution of responses from each dilution a normal (bell shaped curve) distribution? Do any end dilutions show no little or no spread in its distribution, indicating reaction or signal saturation at those doses?...

Track standard dilutions responses from pools of 6, 12, 20 and 30 assays. Are there non-monotonic regions, or hooks, at either end? What is the variation between the dilution responses of multiple assays? What is the dose range of dilution responses that has the most...

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...
