MLR's with Flow Rozenkov at
Sun Nov 20 02:51:44 EST 2005

Dear Don,

MLR by flow can be tested by staining responder cells (pre culturing) with cell division
tracking dyes, such as CFSE. Optionally, APC can also be stained with another dye, e.g.

Before running on flow cells can be stained with antibodies, depending on the number of
remaining channels on your cytometer (CFSE runs in FL1 and PKH26 in FL2) to distinguish
proliferation of subsets.

Please let me know if you are interested in details.
