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

Alkali Scientific IPTG [Isopropyl β D thiogalactopyranoside], Dioxane Free, 100 Grams (Glass Bottle)
IPTG (Isopropyl β-D-Thiogalactoside) is a widely used inducer in molecular biology applications, particularly for the expression of recombinant proteins in bacterial systems. The 100g bottle provides an ample supply for large-scale experiments or ongoing research. IPTG functions by inducing gene expression in systems that utilize the lac operon, where it activates transcription without being metabolized by the host cell. This reagent is essential for protein expression studies, gene regulation experiments, and enzyme production in bacterial cultures. IPTG is commonly used in cloning, protein purification, and research on gene expression systems, helping scientists produce proteins for analysis or therapeutic use.
