生物活性

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

体外研究
(In Vitro)

LAH4 TFA is capable of complexing DNA, associating with the cell surfacemembrane and then, when enveloped within an endosome, disrupts the endosomal membrane as the pH drops[1].
LAH4 TFA possesses robust plasmid DNA transfection properties. Peptides of the LAH4 family are able to efficiently deliver siRNAs in vitro into a human cell line[2].
LAH4 TFA is found to mediate the intracellular delivery of both protein and nucleotide cargo and facilitate protein internalization using mechanisms involving endosomal acidification and processing through the proteasome pathway, leading to enhanced cross presentation of protein antigen by dendritic cells to CD8+ T cells. LAH4 TFA also improves the internalization of CpG, resulting in NF-kB activation, thus potentiating the adjuvant effect of CpG[3].
LAH4 TFA exhibits antibiotic activities against Escherichia coli and Bacillus subtilis. the peptide does not, however, lyse human red blood cells at bacteriocidal concentrations. The antibiotic activities of LAH4 TFA are 2 orders of magnitude more pronounced at pH 5 when compared with pH 7.5[4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
