Magnetic Beads

We have made extensive use of the Miltenyi system with good results for both
depletion and enrichment experiments.  The beads do not seem to interfere
with functional assays or the ability of the cell types we are studying to
mediate their function in vivo.

The largest drawback is, if you use their complete MACS system, it requires
a fairly hefty up-front expenditure because the magnet is expensive.
