Protocol for the isolation and culture of microglia, astrocytes, and neurons from the same mouse brain.

Studying the intrinsic properties of microglia, astrocytes, and neurons is essential to our understanding of brain function. Here, we present a protocol to isolate and culture these neural cells from the same mouse brain. Using immunocapture magnetic beads, we describe steps for dissociating, cleaning, and sequentially separating brains from 9-day-old mice into microglia, astrocytes, and neurons. Following these detailed procedures for seeding and culturing of isolated cells, we can address critical questions related to brain function.
