A monoclonal anti-glycophorin A might  serve your purpose. It recognizes
erythroblasts (arising just after the CFU-E stage) to mature erythrocyte. 
Dako #M0819 for formalin-fixed, paraffin-embedded tissue.

	Hi All,
	           Here's one for any ex ( or current )  vampires amongst
you.
	Anyone know of a method for demonstrating reticulocytes in paraffin
	sections ??  It will be on a block of placenta,  with routine
processing
	and buffered formalin fixation.
		Thanks for any and all help,
