Peg lipid
PEG-lipid is a type of lipid compound that incorporates polyethylene glycol (PEG) into its structure. PEG-lipids are used in the formulation of liposomal and other lipid-based drug delivery systems to improve the pharmacokinetic properties of the encapsulated or associated drugs.

For LNP production, D-Lin-MC3-DMA (MedChemExpress), DSPC (Avanti Polar Lipids), cholesterol (Sigma), and PEG-lipid (Avanti Polar Lipids) were solubilized in ethanol respectively and mixed with a molar ratio of 50:10:38.5:1.5. The lipid mixture was then mixed with an aqueous buffer (50 mmol/L citrate buffer [pH 4.0]), reaching the final lipid concentration of 7.37 mg/mL. Then the lipid mixture and mRNA were added into the NanoAssemblr™ with the volume ratio of 1:3 to obtain mRNA-LNP. Then the diluted LNP-encapsulated mRNA samples were concentrated to appropriate volume and passed through 0.22 μm filters. The produced mRNA-LNP was stored at 4 °C until use. The encapsulation efficiency was measured with the Quant-iT RiboGreen RNA Assay Kit (Life Technologies) using a microplate reader.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
