What can you do with mass photometry?
Our technology is transforming research in a wide range of fields.
AAVs
Precisely characterize AAV preparations by accurately determining empty versus full capsid ratios, aggregation states, and overall integrity. Crucial for optimizing production and ensuring the safety and efficacy of gene therapies.
AdVs
Gain direct, label-free insights into AdV quality by assessing particle concentration, aggregation, and purity. This enables better control over manufacturing processes for gene delivery vectors and oncolytic agents.
Antibody aggregation
Accurately detect and quantify antibody aggregates in solution – faster and with far less sample than SEC and AUC. Essential for optimizing formulation conditions, improving stability, and ensuring safe, effective biotherapeutics.
Antibody characterization
Comprehensively profile bispecific and multi-specific antibody-antigen interactions, including stoichiometry. Ideal for new modalities, complements SPR and BLI, aiding experimental design and the interpretation of data on multi-component systems.
Membrane protein analytics
Analyze membrane proteins in native-like environments, determining oligomeric states, complex formation, and sample purity. Critical for advancing structural studies, functional assays, and therapeutic development.
mRNA
Characterize mRNA integrity and its formulation in lipid nanoparticles (LNPs). Assess size distribution, encapsulation efficiency, and stability of mRNA-LNP complexes, vital for developing and quality controlling mRNA-based vaccines and therapies.
Protein interactions
Directly measure complex formation, stoichiometry, and binding strength to reveal how proteins interact in solution. Vital for understanding biological mechanisms, validating targets, and accelerating drug discovery.
Lentivirus populations
Our advanced single‑particle analysis reveals population heterogeneity and sample purity. It delivers precise, multiparametric data by simultaneously measuring particle size and mass-related contrast.
