logit

In competitive binding assays, the logit-log dose relationship, in which the response is defined by: R=logit(y)=log10(y1y) where y=bb0 with b = fraction of tracer bound and b0 = value of b with no unlabelled ligand in the system. Logit transformed assay data frequently yield straight-line dose-response curves, amenable to statistical analysis.
