Cys-LT7

C₄₄H₆₅N₁₅O₁₀S · 996.15 g/mol

Cys-LT7 is an N-terminal cysteine-modified analog of the phage-display-derived LT7 peptide (HAIYPRH), a homing ligand for the human transferrin receptor (TfR). It is supplied as a conjugation-ready research reagent for building TfR-targeted drug-delivery systems, peptide-drug conjugates, and functionalized nanocarriers, with research applications spanning glioblastoma, hepatocellular-carcinoma, and lung-carcinoma cell-line and delivery-mechanism studies.
