PEG & Vaccines Solutions

Polyethylene glycol (PEG) is a synthetic polymer widely used in many industries and pharmaceutical formulations due to its recognized safety and diverse physicochemical properties. Presently, two novel COVID-19 vaccines based on mRNA-lipid nanoparticles widely used in the world all contain lower doses of PEG-lipid. PEG activity is critical for maintaining the colloidal stability of nanoparticles in biological fluids and reducing the absorption of these particles by filter organs, which can effectively improve the efficacy and safety of nanoparticles after inoculation. Backed by our scientists' rich knowledge and experience in PEG synthesis, BOC Sciences can provide personalized PEG & vaccines development solutions in a short period of time. We are working on the design, synthesis and application of PEGylation technology for many years. Our researchers can help your vaccine development be more successful by providing PEG-modified lipid nanoparticles.

What is the Role of PEG in Vaccines?

As a stabilizer in nanomedicine preparations, PEG can be coated on solid lipid nanoparticles in vaccines to reduce the particle size of lipid nanoparticles, prevent particle aggregation, increase circulation time, and reduce non-targeted cells uptake. Thus, PEGylation can prolong the biological half-life of biopharmaceuticals while reducing toxicity and improving stability. However, there is growing evidence that PEG is immunogenic when conjugated to macromolecules such as proteins and when used as nanocarriers for liposomes and other drug molecules. Therefore, monitoring the in vivo ADME of mRNA lipid nanoparticle vaccines is very important for other PEG-conjugated drugs.
