Lipid Nanoparticles (LNPs)

Leverage Lipid Nanoparticles for Drug Delivery in Your Formulation

Ensure your nucleic acid cargo is well protected and appropriately delivered with our lipid nanoparticles (LNPs) support services. LNPs are common delivery methods to administer nucleic acid-based therapeutics and are compatible with multiple routes of administration, including intravenous, subcutaneous, and inhaled. These molecules protect nucleic acids from the surrounding environment and target their delivery to the tissue or cell type where action is required. We offer analytical method development, characterization, and testing for both your nucleic acid cargo and LNP products. Additionally, we provide LNP formulation and process development services.

Lipid Nanoparaticle Formulation

While LNP formulations and LNP delivery vehicles are becoming increasingly popular in nucleic acid therapeutic development, there are certain aspects to their behavior and functionality that often require expert support.

Size Distribution
LNPs are able to carry nucleic acids of multiple sizes and chemical identities. However, if the cargo exceeds the recommended dimensions, then the product must be monitored for toxicity risks and encapsulation inefficiencies. Our development team helps determine the hydrodynamic radius, polydispersity, and zeta potential to ensure proper packaging and limiting risks related to toxicity.

Formulating nucleic acids with a mixture of lipids is a stochastic process which requires careful monitoring to ensure an appropriate final formulation and composition. We develop custom methods to achieve the highest resolution and sensitivity for each lipid mixture used during the formulation process.

Encapsulation Efficiency
The dosing of mRNA delivered using LNPs as a vector is determined by mRNA concentration. If encapsulation efficiency is not well controlled, then a fixed dose of nucleic acid may correspond to highly variable dose of lipids. The variability could impact treatment efficacy or induce toxicity due to high lipid doses. To address this, we utilize a panel of orthogonal methods to determine encapsulation efficiency, ensuring robust and reliable control of this critical quality attribute.
