BAmP-TK-12 is a ROS-responsive ionizable lipid designed for tumor-cell mRNA delivery. It features a bis(aminopropyl)piperazine-derived ionizable headgroup and four C12 tails connected through cleavable thioketal linkers. In the reported study, BAmP-TK-12 achieved RFP expression in up to 95% of HeLa cells, comparable to Lipofectamine 3000, with lower cytotoxicity under the tested conditions. ROS-triggered linker cleavage supported intracellular mRNA release in high-ROS tumor cells. When formulated with DUF5 mRNA, the LNP suppressed tumor growth in HCT-116 and A549 xenograft models, supporting its use as a promising preclinical research lipid for stimulus-responsive mRNA delivery.

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.
