A2-Iso5-2DC18 is a didroimidazole-linked lipid, served as potent mRNA delivery vehicle. A2-Iso5-2DC18 can be used for antitumor research, including B16F10 melanoma..
A2-Iso5-2DC18, loaded with mLuc or Cre-recombinase mRNA LNPs (mCre), (0.1 mg/kg and 0.5 mg/kg; s.c.; once a week, for 2 weeks) transfects central antigen presenting cells (APCs) in A14/Cre mRNA mouse model[1].A2-Iso5-2DC18 loaded with OVA mRNA (mOVA) vaccine, (15 μg mOVA per mouse; s.c.; twice dose, once every 5 d) induces a significantly high antigen-specific cytotoxic T lymphocyte (CTL) response, in parallel with robust IFN-ɤ secretion in B16F10 mouse melanoma model[1].
