Abstract
The detailed protocol is used to isolate different cell types from murine brain as glial cells, including microglia, using an enzymatic digestion that minimizes cellular mortality. A Percoll gradient (30% to 80%) separation allows a maximal recovery of isolated murine microglial cells prior to flow cytometry analysis.
