LAH4

• Description :

  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].
