Vantage cell counts

Ken,

  If you sort beads and count after sorting you will get counts as you
suggest routinely. Sort fixed cells into media with 20% FCS and you
will find that your counts will be much closer. If with this test you
still get counts as such then your drop delay is off or your abort
rate is too high.

Good Luck
David



Hi All,
	I'm seeing a discrepancy in what the Vantage sorter tells me it's
sorted and the actual numbers sorted. For example, I sorted for green
calibite beads (30,000) and when I re-ran them to check for purity there
were roughly 15,000 only. Does anyone have the same problem? The purity is
good (99%) and everything else checks out by the book?..Thanks in
advance..Ken
