KC-34(SPC-A9)
Instructions for Use
Product information
KC-34 (SPC-A9) is a novel stereopure, diketopiperazine-based ionizable cationic lipid engineered to overcome traditional liver-restricted delivery, achieving balanced multi-organ mRNA transfection. Upon systemic intravenous administration, its precisely optimized chiral configuration allows the lipid nanoparticles (LNPs) to efficiently cross endothelial barriers and target the bone marrow, offering immense therapeutic potential for in vivo hematopoietic stem cell gene editing. Concurrently, KC-34 mediates robust and long-lasting protein expression in the spleen and lungs with minimal hepatic off-target toxicity. Its stable structure provides excellent biocompatibility and high in vivo tolerance, making it ideal for systemic, multi-dose mRNA therapies.

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.
