We need to isolate *viable* human monocytes from whole blood, with >90% purity, and highest possible yield, of course :-). In the past we have used mono-poly resolving media (Flow Labs), which gives two bands, one containing polynuclear cells, the other containing mononukes. We need to remove the lymphocytes (we have also had a slight problem with some pmn contamination in the mono layer - poly layer, however, has been quite pure). All suggestions warmly welcomed. Email or post. Thanks in advance, dan ============================================================================== S A V E T H E W H A L E S , K I L L O U R U N B O R N ?? ============================================================================== Daniel G.

In the past we have Have you tried flow cytometry? Purity > 90% should be no problem at all, but what exactly do you mean by highest possible yield? Flow will limit you to looking at a couple thousand cells per second, and picking out whatever fraction of the input are monocytes. If flow cytometry alone won't get you the numbers you need, perhaps a two-step procedure will do it? I believe Larry Arnold is at UNC, in the dept of Micro and Immuno. He can fill you in on all the gory details of sorting. Steve Kelley Name: Steve Kelley Internet: kelley@aclcb.purdue.edu Phone: 317 494-8638
