YK-009
Instructions for Use
Product information
YK-009 is an advanced, biodegradable ionizable lipid designed for efficient mRNA delivery. Via intramuscular injection, it demonstrates superior targeting to draining lymph nodes, boosting immune cell transfection for vaccines. When administered intravenously, it distributes to the liver but leverages a highly degradable chemical backbone to ensure rapid clearance post-endosomal escape. This effectively eliminates the risk of long-term tissue accumulation and liver toxicity seen in traditional lipids. Delivering a balance of high transfection efficiency and exceptional biocompatibility, YK-009 is an ideal component for safe and potent lipid nanoparticle (LNP) formulations.

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.
| N/P ratio | Not reported in the verified record |
| Cargo | Not available in the verified record |
| Administration route | Not available in the verified record |
| Animal model | Not available in the verified record |
| Formulation process | Not available in the verified record |
N/P is the molar ratio of specified lipid nitrogen groups to nucleic-acid phosphate groups. A lipid:cargo mass ratio is a different quantity and must not be used as N/P.

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.
