COA of Yoltech lipid 4
Description:
Yoltech lipid 4, a highly efficient ionizable lipid disclosed in patent PCT/CN2023/116607, features a central tertiary amine group flanked by hydrophobic tails—specifically, a bis(2-ethylhexyl) core and a linoleyl (C18:2) chain linked via ester bonds. This structure enables pH-responsive behavior critical for mRNA/LNP delivery: neutral in circulation (reducing toxicity) but protonated in endosomes to facilitate membrane disruption and payload release. In murine studies targeting liver PCSK9, Compound 4 achieved ~90% gene-editing efficiency. Its optimized formulation yields LNPs of 70–150 nm with >90% encapsulation, ideal for hepatocyte-specific delivery.

Handling:
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.
