Titration
Titration — A quantitative analytical method where a reagent of known concentration is added to a sample to determine the concentration of an unknown analyte.
What Is Titration?
Titration is the quantitative addition of a solution of known concentration (titrant) to a solution of unknown concentration (analyte) until the reaction reaches an endpoint. In peptide research, titration is used for concentration determination, binding affinity measurement, and pH adjustment of peptide solutions.
Titration Types in Peptide Research
- ITC: Peptide ligand titrated into receptor solution measures complete binding thermodynamics
- NMR titration: Chemical shift perturbation mapping during ligand addition identifies binding sites
- Fluorescence titration: Peptide added to fluorescently labeled target; fluorescence changes report binding
- pH titration: Determines pKa values of ionizable residues and isoelectric point
