Analyte
Analyte — The specific substance being measured or detected in an analytical procedure such as HPLC or mass spectrometry.
What Is an Analyte?
An analyte is the substance being measured in an analytical procedure. In peptide research, the analyte is typically the target peptide whose identity, concentration, purity, or biological activity is being determined. The analytical method must be validated to demonstrate specificity for the analyte in the presence of matrix components, impurities, and degradation products.
Context-Dependent Analytes
- HPLC purity: Analyte = target peptide peak area vs. total peak area
- ELISA: Analyte = endogenous peptide hormone concentration in blood
- Pharmacokinetics: Analyte = drug peptide concentration in plasma over time
- Biomarker: Analyte = downstream marker of peptide pharmacological effect
