Jeff,
You may want to look at LDS-751. It is a nucleic acid dye not requiring
permeabilization and can be used in whole blood with no lysing.
See the following reference:
Multidimensional Flow Cytometric Blood Cell Differentiation without
erythrocyte lysing, Terstappen, et al. in Blood Cells (1991) 17:585-602.
The dye is available from Exciton, Inc (513) 258-3937, Dayton, Ohio.
Good luck.
