Neurodegenerative diseases, such as Alzheimer's and Parkinson's, both involve an accumulation of protein aggregates [1],[2]. Monitoring and studying small oligomers, which are present in the early stages of disease, can be challenging, due to their transient and heterogeneous nature [1].

Lipoprotein lipase (LPL) has long been a focal point in the study of lipid metabolism. Its role in releasing free fatty acids from triglycerides, allowing their transport across cell membranes, is vital for energy production, while dysregulation of this enzyme has been linked to cardiovascular disease [1].

Dr. Martin E. and Dr. Marie A. are experienced scientists – characterizing antibody and gene therapy samples at one of the top 5 pharmaceutical companies. Their lab recently acquired a TwoMP Auto mass photometer and they spoke to us about their initial experience with the instrument and how they are using mass photometry to overcome their analytical challenges.

Shelterin is a DNA-binding complex that facilitates telomeric DNA replication and maintenance of telomeric stability 1. Mutations in shelterin components can lead to various pathologies, including cancer predisposition and premature aging.

AAV sample characterization is a critical step in research, development and manufacturing processes of gene therapies involving these viral vectors (Figure 1). There are several analytical approaches available to assess critical quality attributes (CQAs) for AAV samples, such as capsid content (empty/full ratios) and titer.

Assessing AAV capsid content is critical for AAV research, development and production. There is an urgent need for reliable techniques that can characterize AAV samples efficiently and accurately, particularly when AAV sample loading shows a high level of heterogeneity [1].
