Re: Murine microglia help

From:Geoff McAuliffe

HI Brett:

    Both Mac1 and F4/80 work well on mouse microglia, activated or not. I use frozen sections of paraformaldehyde fixed, cryoprotected brain and  a Vector ABC Elite kit with DAB + nickel and cobalt. Both antibodies are considered quite specific for markers found on mouse microglia and macrophages. I have also stained Kupffer cells in mouse liver with Mac1.
    I have not had success with lectins with mouse microglia although they seem to work well on rat microglia. The lectins that do stain rat microglia (Griffonia something or other) also stain small, unmyelinated fibers in spinal cord so specificity is a problem there.
