sticky antibody

We are currently using a Pharmingen anti-CD99 antibody to stain a CD34+
cells from cord blood. However, it seems to be causing the cells to clump,
while the same cells, stained with different antibodies are fine. It's a
mouse IgG2a. Does anybody have any idea about why this is happening, or how
we could stop it, as it is causing us to lose large numbers of precious cells.

Thanks in advance,
