DMT7 (pKa 6.5) is an ionizable cationic lipid engineered for co-delivery of mRNA and immunomodulators via LNPs. In 4T1 breast cancer metastasis models, DMT7 LNPs carrying IL-12 mRNA and STING agonist MSA-2 significantly reduce tumor burden and pulmonary metastases while modulating T cell populations. The formulation demonstrates broad immunotherapeutic effects in melanoma models, shifting tumor macrophages toward the M1 phenotype, reducing Tregs, and elevating pro-inflammatory cytokines (IL-12, IL-2, TNF-α, IFN-γ).

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
