Hi, I have read some stuff about using "immunosubtraction'' to develop
antibodies specific to certian stages of hematopoiesis.  The idea was to
make polyclonal sera against one cell type, and absord the sera against
the cells you want to exclude,  before going on to make monoclonal
antibodies.  I realize you are after something a little bit different, but
maybe there's information  you can use in these papers. Anyway the best
references I have are

1) Kornfeld S. (1983) Cell Surface antigens on avian erythroid cells:
their expression at various stages of differentiation. Expl Cell Res. 150,

2) Kornfeld S., Beug H., and Graf T. (1983) Detection of avian
haematopoietic cell surface antigens with monoclonal antibodies to myloid
cells: their distribution on normal and luekaemic cells of various
linneages. Expl Cell Res. 143, p383

Good Luck,
