Dose-Response Curve
Dose-Response Curve — A graphical representation of the relationship between the concentration of a compound and the magnitude of its biological effect.
What Is a Dose-Response Curve?
A dose-response curve plots the biological effect of a peptide as a function of its concentration, typically producing a sigmoidal (S-shaped) curve when plotted on a log scale. The curve defines the peptide's potency (EC50/IC50), efficacy (Emax), and Hill slope (cooperativity).
Parameters
- EC50/IC50: Concentration at 50% maximum effect. Defines potency
- Emax: Maximum achievable effect. Defines efficacy
- Hill slope: Steepness of curve. n=1 for simple binding; n>1 indicates cooperativity
- Fitting: 4-parameter logistic (4PL) regression for standard curve fitting
