# Peptide mapping

Peptide mapping is an analytical technique in which a protein or large peptide is digested with a specific protease, and the resulting fragments are separated and identified, usually by LC-MS. The pattern serves as a fingerprint confirming identity and can reveal modifications or sequence variants.
