Validation of an HPLC-CAD method for measuring the lipid content of novel LNP-encapsulated COVID-19 mRNA vaccines
Lipid nanoparticles (LNPs) are frequently employed as mRNA vaccine delivery vehicles. LNPs are made up of four types of lipids: cationic lipid, PEG-lipid conjugate, zwitterionic helper phospholipid, and cholesterol. LNP distribution efficiency is significantly impacted by lipid composition, which also controls LNP stability and bilayer fluidity. The various lipids used in the formulation system have distinct properties and contents. To aid in the development of new drugs and vaccines, we developed and validated an HPLC-CAD method for identifying and determining the amounts of four lipids in Yuxi Watson Biotechnology Co., Ltd.'s LNP-encapsulated COVID-19 mRNA vaccines (OmicronXBB.1.5).
期刊介绍：
The Journal of Virological Methods focuses on original, high quality research papers that describe novel and comprehensively tested methods which enhance human, animal, plant, bacterial or environmental virology and prions research and discovery.
The methods may include, but not limited to, the study of:
Viral components and morphology-
Virus isolation, propagation and development of viral vectors-
Viral pathogenesis, oncogenesis, vaccines and antivirals-
Virus replication, host-pathogen interactions and responses-
Virus transmission, prevention, control and treatment-
Viral metagenomics and virome-
Virus ecology, adaption and evolution-
Applied virology such as nanotechnology-
Viral diagnosis with novelty and comprehensive evaluation.
We seek articles, systematic reviews, meta-analyses and laboratory protocols that include comprehensive technical details with statistical confirmations that provide validations against current best practice, international standards or quality assurance programs and which advance knowledge in virology leading to improved medical, veterinary or agricultural practices and management.
