Single-molecule microscopy in zebrafish embryos
Supervisor: Dr. Marcel J.M. Schaaf, co-supervisors: local: Prof. Dr. Annemarie Meijer, external: Dr. Pablo Loza (P6)
Capitalising on our recent success at studying individual membrane protein mobility in the skin epidermis of zebrafish embryos using single-molecule microscopy, ESR3 will develop new strategies for protein tagging with the Atto647 dye using the Halo-tag system and extend single molecule microscopy to:
- non-membrane proteins in cells of the outer epithelial cell layer of the embryos.
- proteins within leukocytes during mycobacterial infections in the tail fin since it is only a few cell layers thick.
- New near-TIRF setup to study the dynamics of non-membrane signalling proteins in outer epithelial cells of the embryos
- New light sheet and 2-photon microscopy setup to image single molecules (autophagy LC3, chemokines & receptors) in embryos and their dynamics in leukocytes during immune response.
