DMT7
Instructions for Use
Product information
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).

Formulation & study context
Literature information refers to the cited study and its particular formulation. Administration routes are research context, not clinical instructions or a guarantee of performance.
A complete product-specific formulation has not been verified. No standard ratio is substituted.

Provided that storage conditions are as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 1 year.
Wherever possible, prepare and use solutions on the same day. If stock solutions must be prepared in advance, store them as aliquots in tightly sealed vials at -20°C. Generally, these will be usable for up to one month.
Before use, and prior to opening the vial, allow the product to equilibrate to room temperature for at least 1 hour.
