Applications and examples | DLin-MC3-DMA is a fully synthetic ionizable cationic lipid that is suitable for liposomal formulations of DNA,RNA, and various nucleic acid drugs. Compared to conventional cationic lipids, it significantly improves nucleic acid drug encapsulation efficiency and transfection efficiency, making it an excellent membrane material for cationic liposomes. It has been widely used in the research and clinical applications of RNA drug liposomes and is utilized in the marketed siRNA liposome product, Onpattro. |

Package sizes | 1g, 5g |
Storage condition | The product should be stored and transported under an inert gas atmosphere, in a sealed and light-protected container at a temperature of −20 ± 5°C. It should be kept away from strong oxidizing agents. Retest every 12 months when stored properly. |
1. Ketoksikan rendah: DLin-MC3-DMA adalah lipid ionizable pH-responsif, di mana ia mengamalkan caj positif pada pH yang rendah dan mempunyai caj berhampiran neutral pada pH fisiologi. Ini bermakna bahawa, apabila membentuk lipid tiny (LNPs) merangkumi asid nukleik di bawah keadaan berasid, ia mempamerkan ketumpatan minimum caj positif dalam aliran darah, mengakibatkan ketoksikan selular yang rendah.
2. Kecekapan tinggi: LNPs dibentuk dengan DLin-MC3-DMA mempamerkan caj positif, memudahkan lysosomal SiRNA melarikan diri untuk meningkatkan kecekapan transfection dan mengurangkan phagocytosis oleh macrophages.
DLin-MC3-DMA adalah cecair berminyak berwarna kekuningan dengan pKa 6.44. Aktiviti fungsian LNPs korelasi dengan nilai pKa lipid kationik yang digunakan. LNPs ditubuhkan dengan DLin-MC3-DMA dengan pKa 6.2 untuk 6.5 mempamerkan aktiviti gen-silencing yang lebih tinggi.
