Undiluted LNP formulation encapsulating mRNA (0.1 mg/mL)

Description

General description

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.

Analysis Note

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):

  • DMG-PEG2000 - Synthechol
  • DSPC: 1,2-distearoyl-sn-glycero-3-phosphocholine
  • MC3: DLin-MC3
  • DMA (or DODMA)
