Medchemexpress LLC Gala | 107658-43-5 | 99.04% | 3032.36 | 10 MG
GALA is a pH-responsive amphipathic peptide composed of 30 amino acids, functioning as a lung endothelium-targeting ligand. It transitions from a random coil to an α-helix in an acidic environment (pH 5.0), leading to endosomal membrane destabilization and fusion. GALA-modified liposomes cross lung endothelial cells via clathrin-dependent endocytosis and transcytosis, accumulating specifically in the lungs after intravenous injection.
- Enhances cytosolic release of cargos from exosomes, plasmids, and liposomes
- Improves gene transfection efficiency and drives gene knockdown of functional macromolecules (e.g., siRNA) in alveolar epithelial cells
- Vital tool for studying lung cancer metastasis and lung-targeted drug delivery systems
- No significant cytotoxicity at effective concentrations
