Methoxy PEG Ditetradecylamino

Please contact us at for a quotation for large scale GMP manufacture of Methoxy PEG Ditetradecylamino (M-PEG-DTDA) for lipid nanoparticles (LNPs).


JenKem Technology provides large scale GMP manufacture of Methoxy PEG Ditetradecylamino (M-PEG-DTDA) with high purity (97%, and higher) for commercial pharma applications and clinical trials. Methoxy PEG Ditetradecylamino (M-PEG-DTDA) is a high-quality activated PEG for Lipid Nanoparticles (LNPs).

LNP drug delivery systems are commonly employed for nucleic acid delivery. LNPs are generally believed to combine with the cell membrane through noncovalent affinity and absorbed by endocytosis. After being absorbed by the cell, the mRNA delivered by LNPs are released to the cytoplasm and express the target protein, escaping from the endocytosis. This technology has been adopted by pharmaceutical companies in the recent years for COVID-19 vaccine manufacture1.
