CSi12N3 is a bioorthogonally activatable ionizable lipid containing two cleavable silyl-ether-linked C12 tails and a dual-amine headgroup. Formulated as SiLNPs, it remains relatively silent before activation but undergoes Phe-BF3-triggered desilylation, nanoparticle destabilization, and accelerated cytosolic mRNA release. The reported formulation produced up to 44-fold higher mRNA expression than SM-102 LNPs in vitro, with an approximately 10-fold activation-to-silent ratio. In a B16-F10 melanoma model, CSi12N3-based SiLNPs delivering GDNT mRNA induced tumor-localized pyroptosis and inhibited tumor growth without detectable systemic toxicity in the reported study. CSi12N3 is therefore a promising preclinical research lipid for externally controlled, tumor-selective 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.
