Hi!

I am forwarding a request from an investigator who uses our 4-color Coulter
XL flow cytometer. Our core has lots of experience in phenotyping mouse
blood, but little to no experience with human blood. And we are finding it
more difficult to identify monocytes in human blood than in mouse blood.
Therefore, we are seeking advice/suggestions.

Her request is below. You may reply to me and I will forward all messages to
her.

Thanks in advance

We are trying to determine leukocyte counts and differentials in FROZEN
human whole blood samples and are looking for some feedback/input. We are
currently using CD45, CD15 and CD11b in order to enumerate monocytes and
granulocytes, but we are having some trouble. It appears that CD11b is also
staining some of our lymphocytes. We are considering adding CD14 to look at
monocytes, but are wondering if this is the best marker to identify
monocytes. We are also considering dropping CD11b or replacing it with
another marker. All suggestions would be greatly appreciated.
