Learn how to capitalize on the advantages of scalable methods for separation of different biomacromolecules
Understand the benefits of highly tunable chromatographic methods
Discover how to enable a high degree of automation in LNP downstream processing
Optimize LNP formulations and enable their comprehensive analysis

Lipid nanoparticles (LNPs) have emerged as the foremost non-viral carriers for therapeutics and vaccines, capable of encapsulating various payloads. LNP carriers provide a significant advantage over traditional viral delivery systems, enabling modularity, speed, and better scalability. However, they pose significant challenges in terms of their purification and characterization.

Post-formulation, LNPs require downstream processing to make the formulation applicable for in vivo applications and monitoring of CQAs. Analytical methods for process monitoring and QC analytics of LNPs are mostly offline and require disassembling the particles into individual components beforehand. The process of formulation and purification can be monitored by chromatographic methods using monolithic columns. More specifically, two-dimensional chromatographic analytics enables direct analysis of LNP formulation, without any sample pre-treatment. Multiple detectors allow for the determination of encapsulation efficiency, nucleic acid content, nucleic acid integrity, and separation of co-encapsulated cargos in a single chromatographic run. Additional chromatographic methods that further address the heterogeneity of LNPs by utilizing different monolithic column chemistries and buffer effects are presented.

2nd Bacteriophage Therapy Summit 2020 (digital event)

Many of the most compelling applications of bacteriophages involve human therapy, some pertinent to gene therapy, others to antibiotic replacement. These applications require removal of host cell contaminants to acceptable levels, including proteins, DNA and, most of all, endotoxins. This presentation will highlight some of the challenges with effective endotoxin removal, and introduce a new chromatography product that achieves good endotoxin removal while maintaining high recovery of bacteriophage. Case study data will be shared documenting the performance of a platform purification method that enable complete bacteriophage purification within a single shift. Fast analytical methods for qualification of raw materials and tracking phages through the steps of a purification process will also be presented.
