• Design and perform experiments for the biophysical characterisation of nanobodies and proteins.
• Determine the affinity of nanobodies and antibodies using biolayer interferometry (BLI).
• Characterize the colloidal and thermal stability of nanobodies, antibodies and other proteins using dynamic light scattering (DLS) and nano-differential scanning fluorimetry (nanoDSF).
• Perform experiments for the biochemical characterisation of nanobodies such as immunoprecipitation, SDS-PAGE and Western blot.
• Lead the development of laboratory reagents based on nanobodies.
• Document data, perform data analysis and summarize experimental results.
• Present data at internal and external meetings.
• Collaborate closely with research groups at companies, universities and CROs.
