| Hazard Information | Back Directory | [Description]
LAH4 is an antimicrobial peptide that strongly interacts with phospholipid membranes, exhibiting in vitro transfection efficiency. LAH4 exhibits potent antimicrobial, nucleic acid transfection and cell penetration activities[1]. LAH4 mediates the transport of functional β-galactosidase, a large tetrameric protein of about 0.5 MDa, into the cell interior[2]. At acidic pH, LAH4 has exhibited a high tendency to interact strongly with and be adsorbed on anionic membrane[3]. | [Uses]
LAH4, an alpha-helix of the designed amphipathic peptide antibiotic, exhibits potent antimicrobial, nucleic acid transfection and cell penetration activities. LAH4 possesses high plasmid DNA delivery capacities. LAH4 has a strong affinity for anionic lipids found in the outer membrane of bacterial membranes[1][2][3]. | [References]
