This video describes a protocol to isolate neurons, macrophages, and microglia from larval zebrafish brains by mechanically disrupting the brain tissue. The purified cell populations can further be used for genomic analysis.
Protocol
All procedures involving human participants have been performed in compliance with the institutional, national and international guidelines for human welfare and have been reviewed by the local institutional review board. 1. Homogenization NOTE: All steps are performed 4 °C. Add 1.5 mL Tricaine (15 mM) to 90 mm Petri dishes containing 50 larvae in 50 mL of E3 embryo medium treated with 200 µM PTU to termin…
