DOTAP methylsulfat is a cationic lipid reagent, a cationic derivative of trimethylammonium, linked to two 18-carbon fatty acid tails, each with a single olefin group. DOTAP methylsulfat can self-assemble with negatively charged ions (such as DNA) to form complexes, which can be adsorbed to the cell membrane surface and enter the cell by electrostatic interaction and endocytosis, respectively. DOTAP methylsulfat promotes endosomal membrane fusion with its own hydrophobic domain, releases DNA into the cytoplasm, and exerts gene delivery function. DOTAP methylsulfat can be widely used in research fields such as gene therapy, cell transfection, and non-viral vector design .

Inflammation/Immunology Cancer

L17E is an attenuated cationic amphiphilic lytic (ACAL) peptide that can be used to deliver a variety of macromolecules, including proteins, antibodies, and DNA nanostructures. L17E inserts and cleaves the membrane structure through electrostatic interaction, enabling intracellular escape. The efficiency of L17E-mediated delivery is strongly correlated with the expression level of KCNN4 (the gene encoding the calcium-activated potassium channel KCa3.1). L17E also promotes the cellular uptake of macromolecules by inducing micropinocytosis. L17E can be further optimized and improved through dimerization strategies and in combination with other delivery systems, such as nuclear localization signal peptides and cell membrane-coated nanoparticles .
