Trp-L1-T4 is a novel tryptophan-derived ionizable lipid that serves as the core functional component of the optimized lipid nanoparticle (TLNP/RLNP) platform. Its primary function is to enable the efficient encapsulation and in vivo delivery of self-amplifying RNA (saRNA) cargo. Specifically, it facilitates high transfection efficiency and cytosolic release of the RNA payload in target follicular helper T (Tfh) cells, with minimal cytotoxicity. This capability is crucial for reprogramming pathogenic Tfh cells into regulatory CAR-Tfh cells, forming the foundation of the study's therapeutic strategy.

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.
