Lipid nanoparticles (LNPs) have emerged as powerful non-viral delivery vehicles for therapeutic products, including nucleic acids and vaccines. In the fields of gene therapy, protein replacement therapy and mRNA-based vaccines against cancer and infectious diseases, LNPs are gaining increasing significance. This Knowledgebase post explores the important features of LNPs and their analysis, emphasizing the crucial role of proper characterization. Additionally, we will delve into the recommended HPLC columns and accessories, as well as HPLC systems that facilitate efficient analysis of LNP composition.


Liquid nanoparticles.pngThe Power of Lipid Nanoparticles (LNPs): LNPs offer several important features that make them ideal for effective therapeutic product delivery:

  1. Enhance encapsulation efficiency: Lipid oligonucleotides within LNPs possess high encapsulation efficiency, preventing the degradation of nucleic acids. This feature ensures the preservation of therapeutic cargo during delivery.
  2. Improve transfection capabilities: LNPs exhibit potent transfection capabilities, enabling efficient delivery of therapeutic payloads. Moreover, they demonstrate low cytotoxicity and reduced immunogenicity, making them safe and suitable for in vivo applications.

Analyzing LNP Composition:

The composition of LNPs plays a vital role in their function and, therefore, must be accurately characterized. Key components of LNPs include ionizable and cationic lipids, cholesterol, phospholipids, and synthetic PEGylated lipids. Among these, ionizable lipids play a crucial role in protecting nucleic acids from nuclease degradation.

HPLC Columns and Accessories for LNP Analysis: To ensure precise and reliable analysis of LNP composition, the use of suitable HPLC columns and accessories is essential. Here are the recommended products for efficient LNP analysis:

  1. Thermo Scientific™ Accucore™ C30 HPLC Column: Ideal for high-resolution separations of hydrophobic, long-chain compounds, the Accucore™ C30 columns employ solid core silica particles. This enables high separation power without imposing high backpressures, making it compatible with more viscous eluents like isopropanol. The C30 stationary phase offers unique shape selectivity, enabling differentiation of structurally related isomers even with highly aqueous mobile phases.
  2. Thermo Scientific™ Accucore™ C30 LC Guard Column: A complementary accessory to the Accucore™ C30 LC Guard Column,  the LC Guard Column provides added protection and prolongs the lifespan of the main column, ensuring consistent and reliable performance.


HPLC systems for LNP Analysis: Choosing the right HPLC system is crucial for efficient analysis of LNPs. Thermo Fisher Scientific offers the following HPLC systems tailored to meet the specific requirements of LNP analysis:

Thermo ScientificVanquish™ Flex UHPLC: This bio-compatible, iron-free system is ideal for analyzing LNPs containing metal-chelating phosphate groups present in the lipid formulation. It guarantees the sensitivity and recovery requires for robust analysis.
