ALC-0159
Based on 20 publication(s) in Google Scholar
ALC-0159 presents highly mobile surface PEG chains in a dense brush-like conformation, which can form a hydrophilic barrier, reduce non-specific protein adsorption and macrophage uptake, improve colloidal stability, prolong in vivo circulation time, and affect the cellular uptake of LNPs. ALC-0159 dissociates from the surface of mRNA-LNPs under long-term mechanical oscillation stress, thereby reducing steric hindrance, inducing mRNA-LNP fusion, increasing particle size, and releasing unencapsulated mRNA.

Activité biologique
ALC-0159 (GMP) can serve as a PEG-lipid component for the preparation of mRNA-loaded LNPs and MSC-Hyb NPs derived from extracellular vesicles of human mesenchymal stem cells; such LNPs are capable of delivering COL1A1 mRNA to diseased human tendon stem/progenitor cells (TSPCs)[1].
ALC-0159 (GMP) achieves 90% PEG coating efficiency on intact COMIRNATY mRNA‑LNP, and the PEG chains on the LNP surface have high mobility; it forms a dense brush‑like PEG conformation on the LNP surface[2].
ALC-0159 (GMP) (under shaking‑induced mechanical stress) exhibits decreased PEG signal and mobility on mRNA‑LNPs, triggers LNP aggregation and particle size increment, forms large liposome‑like structures accompanied by free mRNA release, which indicates the detachment of ALC‑0159 from the LNP surface[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

DMSO : 100 mg/mL (Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Ethanol : ≥ 50 mg/mL
* "≥" means soluble, but saturation unknown.
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
