As Liz mentioned, F4/80 (a pan macrophage marker) will work. I've been
using Serotec's in frozen sections and it works fine for DAB staining.
Not very strong signal though when I used for fluorescence double
labeling. Some people also use anti-CD11b. I used it a couple times but
in my hands didn't work.
