Isolation kortikaler Mikroglia mit bewahrten Immunophänotyp und Funktionalität aus Murine Neugeborene

Overview

This article describes a procedure for isolating cortical microglia from murine neonates, emphasizing the importance of preserving microglial immunofunction during the process. The isolation method involves micros dissecting brain tissue, culturing mixed glial cells, and subsequently isolating microglia for experimentation.
