B Cell specific antibodies

[Nancy McNelly]

We are looking for information on antibodies to specific to rat
B cells, particulary early progenitor and pre-B cells.  We have
been using a monoclonal (anti-CD45RA from clone HIS24, Pharmingen,
San Diego, CA) that, in theory, is specific for such cells in rat,
but we've had cross-reactions with granulocytes in our preparations.
Has anyone out there had any experience with HIS24?  Does anyone know
of another antibody that might work?  Any info. would be appreciated.
