说明
一般描述
Lipid nano particles (LNP) are used as protective capsules to deliver nucleic acid to target cells, e.g. In COVID-19 vaccines, an mRNA was encapsulated.
分析说明
For in-production and final quality control, determination of LNP content is of interest. Here four lipids were determined by HPLC-CAD (Charged Areosol Detector) in an undiluted LNP formulation encapsulating an mRNA (0.1 mg/mL):
