kkallalalhhlahlalhlalalkka acetate

LAH4 acetate is the α-helical structure of the designed amphoteric peptide antibiotic, which is capable of complexing DNA, associating with the cell surface membrane and wrapped in the endosome, which is destroyed with the decrease of pH value. It has strong antibacterial, nucleic acid transfection and cell penetration activities. LAH4 acetate has high plasmid DNA transmission capacity. LAH4 acetate has a strong affinity for anions in bacterial membranes.

The a-helix of the amphipathic peptide antibiotic LAH4 (KKALLALALHHLAHLALHLALALKKA-NH2) strongly interacts with phospholipid membranes, demonstrating in vitro transfection efficiencies comparable to those of commercially available reagents.

LAH4 TFA, an alpha-helix of the designed amphipathic peptide antibiotic, exhibits potent antimicrobial, nucleic acid transfection, and cell penetration capabilities, along with high plasmid DNA delivery capacities, and shows a strong affinity for anionic lipids in bacterial outer membranes [1] [2] [3].
