The technique of static light scattering (SLS) measures absolute molecular weight using the relationship between the intensity of light scattered by a particle and its molecular weight and size. In general, larger particles scatter more light than smaller particles from a given light source, and the intensity of the scattered light is proportional to the molecular weight of the particle. Dynamic light scattering (DLS) is a well-known technique for determining sample interactions, particle size, and aggregation of molecules dispersed or dissolved in solution. This technique can also be a reliable method for characterizing protein stability.
Both DLS and SLS are valuable technique utilized by our experienced Biophysics and Biotherapeutics teams at Eurofins Discovery. Using our high-throughput microfluidic SLS/DLS/UV-vis instruments from Unchained Labs’ Uncle and Stunner, we can use microliter quantities of samples to measure:
- Concentration and molecular weight
- Aggregation
- Viscosity
- Viral titer
- Viral aggregation
- LNP particle size/distribution
- Viscosity
- Turbidity
- Isothermal stability
- Tm/Tagg
- …and much more!
