Lipid D-2
Instructions for Use
Product information
D-2 is a novel, custom-synthesized ionizable cationic lipid that serves as the core functional component of the targeted lipid nanoparticle (LNP) delivery system. Its key function is to enable the efficient in vivo delivery of therapeutic mRNAs. Under acidic conditions, it ionizes to a positive charge, allowing it to complex with and encapsulate the negatively charged mRNAs encoding the anti-FAP CAR and Lgmn protease. At physiological pH, it returns to a neutral state, which helps reduce systemic toxicity and is crucial for promoting the release of the mRNA payload inside the target macrophages within the infarcted heart. As part of the optimized LNP formulation, D-2 is fundamental for achieving high transfection efficiency, thereby enabling the in situ generation of efferocytosis-boosted CAR-Ms to treat cardiac fibrosis.

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.
