[Histonet] Distinguishing monocytes from granulocytes

[Ramesh Subrahmanyam]

Hello Histonetters,
I am trying to distinguish immature monocytes from immature granulocytes 
in Balb/c mice. Can anyone suggest antibodies for FACS or 
immunohistochemistry or RT-PCR markers that would help in this? 
Suggestions on other methods would be welcome too.
Thanks in advance,
